1. The key to landing your consulting job.

Case interviews - where you are asked to solve a business case study under scrutiny - are the core of the selection process right across McKinsey, Bain and BCG (the “MBB” firms). This interview format is also used pretty much universally across other high-end consultancies; including LEK, Kearney, Oliver Wyman and the consulting wings of the “Big Four”.

If you want to land a job at any of these firms, you will have to ace multiple case interviews.

It is increasingly likely that you will also have to solve online cases given by chatbots etc. You might need to pass these before making it to interview or be asked to sit them alongside first round interviews.

Importantly, case studies aren’t something you can just wing . Firms explicitly expect you to have thoroughly prepared and many of your competitors on interview day will have been prepping for months.

Don’t worry though - MCC is here to help!

This article will take you through a full overview of everything you’ll need to know to do well, linking to more detailed articles and resources at each stage to let you really drill down into the details.

As well as traditional case interviews, we’ll also attend to the new formats in which cases are being delivered and otherwise make sure you’re up to speed with recent trends in this overall part of consulting recruitment.

Before we can figure out how to prepare for a case interview, though, we will first have to properly understand in detail what exactly you are up against. What format does a standard consulting case interview take? What is expected of you? How will you be assessed?

2. What is a case interview?

Before we can hope to tackle a case interview, we have to understand what one is.

In short, a case interview simulates real consulting work by having you solve a business case study in conversation with your interviewer.

This case study will be a business problem where you have to advise a client - that is, an imaginary business or similar organisation in need of guidance.

You must help this client solve a problem and/or make a decision. This requires you to analyse the information you are given about that client organisation and figure out a final recommendation for what they should do next.

Business problems in general obviously vary in difficulty. Some are quite straightforward and can be addressed with fairly standard solutions. However, consulting firms exist precisely to solve the tough issues that businesses have failed to deal with internally - and so consultants will typically work on complex, idiosyncratic problems requiring novel solutions.

Some examples of case study questions might be:

• How much would you pay for a banking licence in Ghana?
• Estimate the potential value of the electric vehicle market in Germany
• How much gas storage capacity should a UK domestic energy supplier build?

Consulting firms need the brightest minds they can find to put to work on these important, difficult projects. You can expect the case studies you have to solve in interview, then, to echo the unique, complicated problems consultancies deal with every day. As we’ll explain here, this means that you need to be ready to think outside the box to figure out genuinely novel solutions.

2.1. What skills do case interviews assess?

Reliably impressing your interviewers means knowing what they are looking for. This means understanding the skills you are being assessed against in some detail.

Overall, it’s important always to remember that, with case studies, there are no strict right or wrong answers. What really matters is how you think problems through, how confident you are with your conclusions and how quick you are with the back of the envelope arithmetic.

The objective of this kind of interview isn’t to get to one particular solution, but to assess your skillset. This is even true of modern online cases, where sophisticated AI algorithms score how you work as well as the solutions you generate.

If you visit McKinsey , Bain and BCG web pages on case interviews, you will find that the three firms look for very similar traits, and the same will be true of other top consultancies.

Broadly speaking, your interviewer will be evaluating you across five key areas:

2.1.1.One: Probing mind

Showing intellectual curiosity by asking relevant and insightful questions that demonstrate critical thinking and a proactive nature. For instance, if we are told that revenues for a leading supermarket chain have been declining over the last ten years, a successful candidate would ask:

“ We know revenues have declined. This could be due to price or volume. Do we know how they changed over the same period? ”

This is as opposed to a laundry list of questions like:

• Did customers change their preferences?
• Which segment has shown the decline in volume?
• Is there a price war in the industry?

2.1.2. Two: Structure

Structure in this context means structuring a problem. This, in turn, means creating a framework - that is, a series of clear, sequential steps in order to get to a solution.

As with the case interview in general, the focus with case study structures isn’t on reaching a solution, but on how you get there.

This is the trickiest part of the case interview and the single most common reason candidates fail.

We discuss how to properly structure a case in more detail in section three. In terms of what your interviewer is looking for at high level, though, key pieces of your structure should be:

• Proper understanding of the objective of the case - Ask yourself: "What is the single crucial piece of advice that the client absolutely needs?"
• Identification of the drivers - Ask yourself: "What are the key forces that play a role in defining the outcome?"

Our Problem Driven Structure method, discussed in section three, bakes this approach in at a fundamental level. This is as opposed to the framework-based approach you will find in older case-solving

Focus on going through memorised sequences of steps too-often means failing to develop a full understanding of the case and the real key drivers.

At this link, we run through a case to illustrate the difference between a standard framework-based approach and our Problem Driven Structure method.

2.1.3. Three: Problem Solving

You’ll be tested on your ability to identify problems and drivers, isolate causes and effects, demonstrate creativity and prioritise issues. In particular, the interviewer will look for the following skills:

• Prioritisation - Can you distinguish relevant and irrelevant facts?
• Connecting the dots - Can you connect new facts and evidence to the big picture?
• Establishing conclusions - Can you establish correct conclusions without rushing to inferences not supported by evidence?

2.1.4. Four: Numerical Agility

In case interviews, you are expected to be quick and confident with both precise and approximated numbers. This translates to:

• Performing simple calculations quickly - Essential to solve cases quickly and impress clients with quick estimates and preliminary conclusions.
• Analysing data - Extract data from graphs and charts, elaborate and draw insightful conclusions.
• Solving business problems - Translate a real world case to a mathematical problem and solve it.

Our article on consulting math is a great resource here, though the extensive math content in our MCC Academy is the best and most comprehensive material available.

2.1.5. Five: Communication

Real consulting work isn’t just about the raw analysis to come up with a recommendation - this then needs to be sold to the client as the right course of action.

Similarly, in a case interview, you must be able to turn your answer into a compelling recommendation. This is just as essential to impressing your interviewer as your structure and analysis.

Consultants already comment on how difficult it is to find candidates with the right communication skills. Add to this the current direction of travel, where AI will be able to automate more and more of the routine analytic side of consulting, and communication becomes a bigger and bigger part of what consultants are being paid for.

So, how do you make sure that your recommendations are relevant, smart, and engaging? The answer is to master what is known as CEO-level communication .

This art of speaking like a CEO can be quite challenging, as it often involves presenting information in effectively the opposite way to how you might normally.

To get it right, there are three key areas to focus on in your communications:

• Top down : A CEO wants to hear the key message first. They will only ask for more details if they think that will actually be useful. Always consider what is absolutely critical for the CEO to know, and start with that. You can read more in our article on the Pyramid Principle .
• Concise : This is not the time for "boiling the ocean" or listing an endless number possible solutions. CEOs, and thus consultants, want a structured, quick and concise recommendation for their business problem, that they can implement immediately.
• Fact-based : Consultants share CEOs' hatred of opinions based on gut feel rather than facts. They want recommendations based on facts to make sure they are actually in control. Always go on to back up your conclusions with the relevant facts.

For more detail on all this, check out our full article on delivering recommendations .

Prep the right way

2.2. where are case interviews in the consulting selection process.

Not everyone who applies to a consulting firm will have a case interview - far from it!

In fact, case interviews are pretty expensive and inconvenient for firms to host, requiring them to take consultants off active projects and even fly them back to the office from location for in-person interviews. Ideally, firms want to cut costs and save time by narrowing down the candidate pool as much as possible before any live interviews.

As such, there are some hoops to jump through before you make it to interview rounds.

Firms will typically eliminate as much as 80% of the applicant pool before interviews start. For most firms, 50%+ of applicants might be cut based on resumes, before a similar cut is made on those remaining based on aptitude tests. McKinsey currently gives their Solve assessment to most applicants, but will use their resulting test scores alongside resumes to cut 70%+ of the candidate pool before interviews.

You'll need to be on top of your game to get as far as an interview with a top firm. Getting through the resume screen and any aptitude tests is an achievement in itself!

For readers not yet embroiled in the selection process themselves, let’s put case interviews in context and take a quick look at each stage in turn. Importantly, note that you might also be asked to solve case studies outside interviews as well…

2.2.1. Application screen

It’s sometimes easy to forget that such a large cut is made at the application stage. At larger firms, this will mean your resume and cover letter is looked at by some combination of AI tools, recruitment staff and junior consulting staff (often someone from your own university).

Only the best applications will be passed to later stages, so make sure to check out our free resume and cover letter guides, and potentially get help with editing , to give yourself the best chance possible.

2.2.2. Aptitude tests and online cases

This part of the selection process has been changing quickly in recent years and is increasingly beginning to blur into the traditionally separate case interview rounds.

In the past, GMAT or PST style tests were the norm. Firms then used increasingly sophisticated and often gamified aptitude tests, like the Pymetrics test currently used by several firms, including BCG and Bain, and the original version of McKinsey’s Solve assessment (then branded as the Problem Solving Game).

Now, though, there is a move towards delivering relatively sophisticated case studies online. For example, McKinsey has replaced half the old Solve assessment with an online case. BCG’s Casey chatbot case now directly replaces a live first round case interview, and in the new era of AI chatbots, we expect these online cases to quickly become more realistic and increasingly start to relieve firms of some of the costs of live interviews.

Our consultants collectively reckon that, over time, 50% of case interviews are likely to be replaced with these kinds of cases. We give some specific advice for online cases in section four. However, the important thing to note is that these are still just simulations of traditional case interviews - you still need to learn how to solve cases in precisely the same way, and your prep will largely remain the same.

2.2.3. Rounds of Interviews

Now, let’s not go overboard with talk of AI. Even in the long term, the client facing nature of consulting means that firms will have live case interviews for as long as they are hiring anyone. And in the immediate term, case interviews are still absolutely the core of consulting selection.

Before landing an offer at McKinsey, Bain, BCG or any similar firm, you won’t just have one case interview, but will have to complete four to six case interviews, usually divided into two rounds, with each interview lasting approximately 50-60 minutes .

Being invited to first round usually means two or three case interviews. As noted above, you might also be asked to complete an online case or similar alongside your first round interviews.

If you ace first round, you will be invited to second round to face the same again, but more gruelling. Only then - after up to six case interviews in total, can you hope to receive an offer.

2.3. Typical case interview format

Before we dive in to the nuts and bolts of case cracking, we should give you a bit more detail on what exactly you’ll be up against on interview day.

Case interviews come in very similar formats across the various consultancies where they are used.

The standard case interview can be thought of as splitting into two standalone sub-interviews. Thus “case interviews” can be divided into the case study itself and a “fit interview” section, where culture fit questions are asked.

This can lead to a bit of confusion, as the actual case interview component might take up as little as half of your scheduled “case interview”. You need to make sure you are ready for both aspects.

To illustrate, here is the typical case interview timeline:

• First 15-30 minutes: Fit Interview - with questions assessing your motivation to be a consultant in that specific firm and your traits around leadership and teamwork. Learn more about the fit interview in our in-depth article here .
• Next 30-40 minutes: Case Interview - solving a case study
• Last 5 minutes: Fit Interview again - this time focussing on your questions for your interviewer.

Both the Case and Fit interviews play crucial roles in the finial hiring decision. There is no “average” taken between case and fit interviews: if your performance is not up to scratch in either of the two, you will not be able to move on to the next interview round or get an offer.

NB: No case without fit

Note that, even if you have only been told you are having a case interview or otherwise are just doing a case study, always be prepared to answer fit questions. At most firms, it is standard practice to include some fit questions in all case interviews, even if there are also separate explicit fit interviews, and interviewers will almost invariably include some of these questions around your case. This is perfectly natural - imagine how odd and artificial it would be to show up to an interview, simply do a case and leave again, without talking about anything else with the interviewer before or after.

2.4. Differences between first and second round interviews

Despite interviews in the first and second round following the same format, second/final round interviews will be significantly more intense. The seniority of the interviewer, time pressure (with up to three interviews back-to-back), and the sheer value of the job at stake will likely make a second round consulting case interview one of the most challenging moments of your professional life.

There are three key differences between the two rounds:

• Time Pressure : Final round case interviews test your ability to perform under pressure, with as many as three interviews in a row and often only very small breaks between them.
• Focus : Since second round interviewers tend to be more senior (usually partners with 12+ years experience) and will be more interested in your personality and ability to handle challenges independently. Some partners will drill down into your experiences and achievements to the extreme. They want to understand how you react to challenges and your ability to identify and learn from past mistakes.
• Psychological Pressure: While case interviews in the first round are usually more focused on you simply cracking the case, second round interviewers often employ a "bad cop" strategy to test the way you react to challenges and uncertainty.

2.5. Differences between firms

For the most part, a case interview is a case interview. However, firms will have some differences in the particular ways they like to do things in terms of both the case study and the fit component.

As we’ll see, these differences aren’t hugely impactful in terms of how you prepare. That said, it's always good to know as much as possible about what you will be going up against.

2.5.1. Candidate led vs interviewer led case formats

Most consulting case interview questions test your ability to crack a broad problem, with a case prompt often going something like:

" How much would you pay to secure the rights to run a restaurant in the British Museum? "

You, as a candidate, are then expected to identify your path to solve the case (that is, provide a structure), leveraging your interviewer to collect the data and test your assumptions.

This is known as a “candidate-led” case interview and is used by Bain, BCG and other firms.

However, a McKinsey case interview - especially in the first round - is slightly different, with the interviewer controlling the pace and direction of the conversation much more than with other case interviews.

At McKinsey, your interviewer will ask you a set of pre-determined questions, regardless of your initial structure. For each question, you will have to understand the problem, come up with a mini structure, ask for additional data (if necessary) and come to the conclusion that answers the question.

McKinsey’s cases are thus referred to as “interviewer-led”. This more structured format of case also shows up in online cases by other firms - notably including BCG’s Casey chatbot (with the amusing result that practising McKinsey-style cases can be a great addition when prepping for BCG).

Essentially, these interviewer-led case studies are large cases made up of lots of mini-cases. You still use basically the same method as you would for standard (or candidate-led) cases - the main difference is simply that, instead of using that method to solve one big case, you are solving several mini-cases sequentially.

2.5.2. The McKinsey PEI

McKinsey brands its fit aspect of interviews as the Personal Experience Interview or PEI. Despite the different name, this is really much the same interview you will be going up against in Bain, BCG and any similar firms.

McKinsey does have a reputation for pushing candidates a little harder with fit or PEI questions, focusing on one story per interview and drilling down further into the specific details each time. We discuss this tendency more in our fit interview article. However, no top end firm is going to go easy on you and you should absolutely be ready for the same level of grilling at Bain, BCG and others. Thus any difference isn’t hugely salient in terms of prep.

2.6. How are things changing in 2023?

For the foreseeable future, you are going to have to go through multiple live case interviews to secure any decent consulting job. These might increasingly happen via Zoom rather than in person, but they should remain largely the same otherwise.

However, things are changing and the rise of AI in recent months seems pretty much guaranteed to accelerate existing trends.

Even before the explosive development of AI chatbots like ChatGPT we have seen in recent months, automation was already starting to change the recruitment process.

As we mentioned, case interviews are expensive and inconvenient for firms to run. Ideally, then, firms will try to reduce the number of interviews required for recruitment as far as possible. For many years, tests of various kinds served to cut down the applicant pool and thus the number of interviews. However, these tests had a limited capacity to assess candidates against the full consulting skillset in the way that case interviews do so well.

More recently, though, the development of online testing has allowed for more and more advanced assessments. Top consulting firms have been leveraging screening tests that better and better capture the same skillset as case interviews. Eventually this is converging on automated case studies. We see this very clearly with the addition of the Redrock case to McKinsey’s Solve assessment.

As these digital cases become closer to the real thing, the line between test and interview blurs. Online cases don’t just reduce the number of candidates to interview, but start directly replacing interviews.

Case in point here is BCG’s Casey chatbot . Previously, BCG had deployed less advanced online cases and similar tests to weed out some candidates before live case interviews began. Now, though, Casey actually replaces one first round case interview.

Casey, at time of writing, is still a relatively “dumb” chatbot, basically running through a pre-set script. The Whatsapp-like interface does a lot of work to make it feel like one is chatting to a “real person” - the chatbot itself, though, cannot provide feedback or nudges to candidates as would a human interviewer.

We fully expect that, as soon as BCG and other firms can train a truer AI, these online cases will become more widespread and start replacing more live interviews.

We discuss the likely impacts of advanced AI on consulting recruitment and the industry more broadly in our blog.

Here, though, the real message is that you should expect to run into digital cases as well as traditional case interviews.

Luckily, despite any changes in specific format, you will still need to master the same fundamental skills and prepare in much the same way.

We’ll cover a few ways to help prepare for chatbot cases in section four. Ultimately, though, firms are looking for the same problem solving ability and mindset as a real interviewer. Especially as chatbots get better at mimicking a real interviewer, candidates who are well prepared for case cracking in general should have no problem with AI administered cases.

2.6.1. Automated fit interviews

Analogous to online cases, in recent years there has been a trend towards automated, “one way” fit interviews, with these typically being administered for consultancies by specialist contractors like HireVue or SparkHire.

These are kind of like Zoom interviews, but if the interviewer didn’t show up. Instead you will be given fit questions to answer and must record your answer in your computer webcam. Your response will then go on to be assessed by an algorithm, scoring both what you say and how you say it.

Again, with advances in AI, it is easy to imagine these automated interviews going from fully scripted interactions, where all candidates are asked the same list of questions, to a more interactive experience. Thus, we might soon arrive at a point where you are being grilled on the details of your stories - McKinsey PEI style - but by a bot rather than a human.

We include some tips on this kind of “one way” fit interview in section six here.

3. What do I need to learn to solve cases?

If you’re new to case cracking. You might feel a bit hopeless when you see a difficult case question, not having any idea where to start.

In fact though, cracking cases is much like playing chess. The rules you need to know to get started are actually pretty simple. What will make you really proficient is time and practice.

In this section, we’ll run through a high level overview of everything you need to know, linking to more detailed resources at every step.

3.1. Business fundamentals

Obviously, you are going to need to be familiar with basic business concepts in order to understand the case studies you are given in the first instance.

If you are coming from a business undergrad, an MBA or are an experienced hire, you might well have this covered already.

However, many consultants will be entering from engineering or similar backgrounds and the major consulting firms are hiring more and more PhDs and non-MBA master's graduates from all subjects. These individuals will need to get up to speed on business fundamentals.

Luckily, you don’t need a degree-level understanding of business to crack interview cases, and a lot of the information you will pick up by osmosis as you read through articles like this and go through cases.

However, some things you will just need to sit down and learn. We cover everything you need to know in some detail in our Case Academy course. However, some examples here of things you need to learn are:

• Basic accounting (particularly how to understand all the elements of a balance sheet)
• Basic economics
• Basic marketing
• Basic strategy

Note, though, that learning the very basics of business is the beginning rather than the end of your journey.

Once you are able to “speak business” at a rudimentary level, you should try to “become fluent” and immerse yourself in reading/viewing/listening to as wide a variety of business material as possible, getting a feel for all kinds of companies and industries - and especially the kinds of problems that can come up in each context and how they are solved.

The material put out by the consulting firms themselves is a great place to start, but you should also follow the business news and find out about different companies and sectors as much as possible between now and interviews. Remember, if you’re going to be a consultant, this should be fun rather than a chore!

3.2. How to solve cases like a real consultant

This is the really important bit.

If you look around online for material on how to solve case studies, a lot of what you find will set out framework-based approaches. However, as we have mentioned, these frameworks tend to break down with more complex, unique cases - with these being exactly the kind of tough case studies you can expect to be given in your interviews.

To address this problem, the MyConsultingCoach team has developed a new, proprietary approach to case cracking that replicates how top management consultants approach actual engagements.

MyConsultingCoach’s Problem Driven Structure approach is a universal problem solving method that can be applied to any business problem , irrespective of its nature.

As opposed to just selecting a generic framework for each case, the Problem Driven Structure approach works by generating a bespoke structure for each individual question and is a simplified version of the roadmap McKinsey consultants use when working on engagements.

The canonical seven steps from McKinsey on real projects are simplified to four for case interview questions, as the analysis required for a six-month engagement is somewhat less than that needed for a 45-minute case study. However, the underlying flow is the same.

This video has more information on how frameworks can be unreliable and how we address this problem:

Otherwise, let's zoom in to see how our method actually works in more detail:

3.2.1. Identify the problem

Identifying the problem means properly understanding the prompt/question you are given, so you get to the actual point of the case.

This might sound simple, but cases are often very tricky, and many candidates irretrievably mess things up within the first few minutes of starting. Often, they won’t notice this has happened until they are getting to the end of their analysis. Then, they suddenly realise that they have misunderstood the case prompt - and have effectively been answering the wrong question all along!

With no time to go back and start again, there is nothing to do. Even if there were time, making such a silly mistake early on will make a terrible impression on their interviewer, who might well have written them off already. The interview is scuppered and all the candidate’s preparation has been for nothing.

This error is so galling as it is so readily avoidable.

Our method prevents this problem by placing huge emphasis on a full understanding of the case prompt. This lays the foundations for success as, once we have identified the fundamental, underlying problem our client is facing, we focus our whole analysis around finding solutions to this specific issue.

Now, some case interview prompts are easy to digest. For example, “Our client, a supermarket, has seen a decline in profits. How can we bring them up?”. However, many of the prompts given in interviews for top firms are much more difficult and might refer to unfamiliar business areas or industries. For example, “How much would you pay for a banking license in Ghana?” or “What would be your key areas of concern be when setting up an NGO?”

Don’t worry if you have no idea how you might go about tackling some of these prompts!

In our article on identifying the problem and in our full lesson on the subject in our MCC Academy course, we teach a systematic, four step approach to identifying the problem , as well as running through common errors to ensure you start off on the right foot every time!

This is summarised here:

Following this method lets you excel where your competitors mess up and get off to a great start in impressing your interviewer!

3.2.2. Build your problem driven structure

After you have properly understood the problem, the next step is to successfully crack a case is to draw up a bespoke structure that captures all the unique features of the case.

This is what will guide your analysis through the rest of the case study and is precisely the same method used by real consultants working on real engagements.

Of course, it might be easier here to simply roll out one an old-fashioned framework, and a lot of candidates will do so. This is likely to be faster at this stage and requires a lot less thought than our problem-driven structure approach.

However, whilst our problem driven structure approach requires more work from you, our method has the advantage of actually working in the kind of complex case studies where generic frameworks fail - that is exactly the kind of cases you can expect at an MBB interview .

Since we effectively start from first principles every time, we can tackle any case with the same overarching method. Simple or complex, every case is the same to you and you don’t have to gamble a job on whether a framework will actually work

In practice, structuring a problem with our method means drawing up either an issue tree or an hypothesis tree , depending on how you are trying to address the problem.

These trees break down the overall problem into a set of smaller problems that you can then solve individually. Representing this on a diagram also makes it easy for both you and your interviewer to keep track of your analysis.

To see how this is done, let’s look at the issue tree below breaking down the revenues of an airline:

These revenues can be segmented as the number of customers multiplied by the average ticket price. The number of customers can be further broken down into a number of flights multiplied by the number of seats, times average occupancy rate. The node corresponding to the average ticket price can then be segmented further.

It is worth noting that the same problem can be structured in multiple valid ways by choosing different means to segment the key issues.

That said, not all valid structures are equally useful in solving the underlying problem. A good structure fulfils several requirements - including MECE-ness , level consistency, materiality, simplicity, and actionability. It’s important to put in the time to master segmentation, so you can choose a scheme isn’t only valid, but actually useful in addressing the problem.

After taking the effort to identify the problem properly, an advantage of our method is that it will help ensure you stay focused on that same fundamental problem throughout. This might not sound like much, but many candidates end up getting lost in their own analysis, veering off on huge tangents and returning with an answer to a question they weren’t asked.

Another frequent issue - particularly with certain frameworks - is that candidates finish their analysis and, even if they have successfully stuck to the initial question, they have not actually reached a definite solution. Instead, they might simply have generated a laundry list of pros and cons, with no clear single recommendation for action.

Clients employ consultants for actionable answers, and this is what is expected in the case interview. The problem driven structure excels in ensuring that everything you do is clearly related back to the key question in a way that will generate a definitive answer. Thus, the problem driven structure builds in the hypothesis driven approach so characteristic of real consulting practice.

You can learn how to set out your own problem driven structures in our article here and in our full lesson in the MCC Academy course.

Join thousands of other candidates cracking cases like pros

3.2.3. lead the analysis.

A problem driven structure might ensure we reach a proper solution eventually, but how do we actually get there?

We call this step " leading the analysis ", and it is the process whereby you systematically navigate through your structure, identifying the key factors driving the issue you are addressing.

Generally, this will mean continuing to grow your tree diagram, further segmenting what you identify as the most salient end nodes and thus drilling down into the most crucial factors causing the client’s central problem.

Once you have gotten right down into the detail of what is actually causing the company’s issues, solutions can then be generated quite straightforwardly.

To see this process in action, we can return to our airline revenue example:

Let’s say we discover the average ticket price to be a key issue in the airline’s problems. Looking closer at the drivers of average ticket price, we find that the problem lies with economy class ticket prices. We can then further segment that price into the base fare and additional items such as food.

Having broken down the issue to such a fine-grained level, solutions occur quite naturally. In this case, we can suggest incentivising the crew to increase onboard sales, improving assortment in the plane, or offering discounts for online purchases.

Our article on leading the analysis is a great primer on the subject, with our video lesson in the MCC Academy providing the most comprehensive guide available.

3.2.4. Provide recommendations

So you have a solution - but you aren’t finished yet!

Now, you need to deliver your solution as a final recommendation.

This should be done as if you are briefing a busy CEO and thus should be a one minute, top-down, concise, structured, clear, and fact-based account of your findings.

The brevity of the final recommendation belies its importance. In real life consulting, the recommendation is what the client has potentially paid millions for - from their point of view, it is the only thing that matters.

In an interview, your performance in this final summing up of your case is going to significantly colour your interviewer’s parting impression of you - and thus your chances of getting hired!

So, how do we do it right?

Barbara Minto's Pyramid Principle elegantly sums up almost everything required for a perfect recommendation. The answer comes first , as this is what is most important. This is then supported by a few key arguments , which are in turn buttressed by supporting facts .

Across the whole recommendation, the goal isn’t to just summarise what you have done. Instead, you are aiming to synthesize your findings to extract the key "so what?" insight that is useful to the client going forward.

All this might seem like common sense, but it is actually the opposite of how we relay results in academia and other fields. There, we typically move from data, through arguments and eventually to conclusions. As such, making good recommendations is a skill that takes practice to master.

We can see the Pyramid Principle illustrated in the diagram below:

To supplement the basic Pyramid Principle scheme, we suggest candidates add a few brief remarks on potential risks and suggested next steps . This helps demonstrate the ability for critical self-reflection and lets your interviewer see you going the extra mile.

The combination of logical rigour and communication skills that is so definitive of consulting is particularly on display in the final recommendation.

Despite it only lasting 60 seconds, you will need to leverage a full set of key consulting skills to deliver a really excellent recommendation and leave your interviewer with a good final impression of your case solving abilities.

Our specific article on final recommendations and the specific video lesson on the same topic within our MCC Academy are great, comprehensive resources. Beyond those, our lesson on consulting thinking and our articles on MECE and the Pyramid Principle are also very useful.

3.3. Common case types and the building blocks to solve them

You should tackle each new case on its own merits. However, that’s not to say there aren’t recurring themes that come up fairly reliably in cases - there absolutely are. Business is business and case studies will often feature issues like profitability, competition etc.

Old fashioned framework approaches would have you simply select a defined framework for each kind of case and, in effect, just run the algorithm and wait for a solution to fall out.

We’ve already explained how frameworks can let you down. In this context, too many candidates will fall into the trap of selecting a framework for that case type that simply won’t work for their specific case.

The counterpoint in favour of frameworks, though, is that they are at least fast and prevent you having to start from the ground up with a common kind of case.

Ideally, you should have the best of both worlds - and this is why, in our articles on this site and in our MCC Academy course, we have developed a set of “building bocks” for common case themes.

As they name suggests, building blocks give you modular components for different kinds of case to help build out your own custom structures faster. These then allow you to leverage the symmetries between cases without inheriting the inflexibility of frameworks.

Let’s take a look at five different case types and get a brief idea of how our building block approach helps you with each. You can find more detail on each in the full length articles linked, as well as in the full-length video lessons in our MCC Academy course.

3.3.1. Estimation

Consultants need to push forward to provide definitive recommendations to clients in a timely manner despite typically not having access to full information on a problem. Estimation of important quantities is therefore at the heart of real life consulting work.

Estimation is thus just as fundamental to case cracking.

A case interview might centre on an estimation question, and this might be quite common for a first round interview. However, estimation is also very likely to be a crucial part of pretty well any other kind of case question you receive is likely to include estimation as a crucial component of your analysis.

The kinds of estimation you might be asked to make in a case interview can be very daunting:

• How many bank branches are there in Italy?
• How many cars are sold in Berlin in one year?
• How many people will buy the latest high-tech smartphone on the market?

You might have no idea where to begin with these examples. However, tempting as it might be, your answer cannot ever be a simple guess .

A decent estimation does have a guessed element - though this should really be an educated guess based on some pre-existing knowledge. However, this guessed element is always then combined with a rigorous quantitative method to arrive at a reasonable estimation.

In context of a case interview, it’s important to realise that your interviewer doesn’t really care about the right answer (they don’t need to ask you to find out, after all). What’s important is showing the rational process by which you get to your answer.

A guess that was somehow exactly correct is no good compared to a “wrong” answer that was reached by a very sensible, intelligent process of estimation. In cases, this method will often be a matter of segmentation.

So, where would we start in working out how many cars are sold in Berlin, for example?

The key to estimation case questions is the ability to logically break down the problem into more manageable pieces. In consulting case studies, this will generally mean segmenting a wider population to find a particular target group. For example, starting from the total population of Berlin and narrowing down to the cohort of individuals who will buy a car that year.

There are usually many ways to segment the same starting population, and several different segmentation schemes might be equally valid. However, it is crucial to choose the specific method best suited to the goal in answering the question and allowing you to best leverage the data you have available.

Segmentation must be allied with assumptions in order to arrive at an estimation. These assumptions are the “guessed” element of estimations we mentioned above. Assumptions cannot just be plucked from thin air, but must always be reasonable .

The example below showcases both the segmentation and assumptions made in an estimation of the size of the wedding planning market in London:

Our articles on estimation and the MECE concept are great starting points in getting to grips with consulting estimation. However, the best place to learn how to make estimations is with the dedicated building block video lesson in our MCC Academy course.

Those of you from physics or engineering backgrounds will probably see a lot in common with Fermi questions . We have plenty of estimation cases for you to work through in our free case library. However, Fermi questions are a great way of getting a little extra practice and you can find a lifetime’s supply online.

3.3.2. Profitability

The fundamental goal of any normal business is to maximise profits - nobody is getting up and going to work to lose money. Even Silicon Valley tech start-ups are supposed to be profitable some day!

Profitability problems are thus bread and butter issues for management consultants.

Clients often tell consultants broadly the same story. The business was doing in well in recent years, with strong profits. However, some recent turn of events has upset the status quo and led to concerns around profit levels. Consultants are brought in as businesses are often sufficiently complex that it can be difficult to figure out precisely where and why the company is losing money - let alone how to then reverse the situation and restore healthy profits.

Despite steady growth in customer flow, the Walfort supermarket chain has seen falling profits in the past year. What is the reason for this decline?

Understanding profitability ultimately means understanding the various components that determine a company’s profit. You will need to learn to decompose profit first into revenues and costs (profit being the synthesis of these two factors). Crucially, you then need to segment further, distinguishing different specific revenue streams and separating various fixed and variable costs.

To take an example, just examining the revenue side of profit, the incoming revenues for an insurance firm might be broken down as follows:

Improving profitability will inherently mean increasing revenues and/or decreasing costs. To solve profitability problems, we thus have to understand the ways we can minimise different costs, as well as ways to drive sales and/or optimise pricing to increase revenue. Importantly, you must be able to judge which of these options is best suited to address specific scenarios.

The key to tackling the complex kind of profitability questions given by MBB-level consultancies lies in this proper segmentation.

By contrast, old-fashioned case interview frameworks will simply have you look at aggregate cost and revenue data before recommending generic cost-cutting or revenue-driving measures. However, this will often lead to negative outcomes in more involved cases, making matters worse for the client.

For example, it might well be that a company actually makes a loss when it serves a certain cohort of customers. An airline, for instance, might lose money on economy class customers but make a healthy profit on each business class customer. Attempts to boost revenue by increasing sales across the board might actually reduce profit further by increasing the number of economy class customers. What is required is targeted measures to increase focus on business class and/or mitigate economy class losses.

You can start learning to segment these kinds of cases properly in our article on profitability , whilst the best way to really master profitability questions is our full lesson on the subject in the Building Blocks section of our MCC Academy course.

3.3.3. Pricing

For a company to be profitable at all, it is a pre-requisite that it charges the right price for whatever it sells. However, establishing what price to charge for any one product - or indeed a whole suite of related products - can be a highly complex business.

Consultants are often engaged to negotiate the many variables, with all their complex interdependencies, at play in pricing. Correspondingly, then, pricing is a common theme in case interviews.

• A company launches a new smartphone with a significantly improved camera. How much should they charge?
• A doughnut chain wants to start selling coffee in their shops. How much should they charge per cup?

Clearly, lot of different factors can influence the answers to these questions, and it can be difficult to know where to start. To get a handle on all this complexity, you will need to take a methodical, structured approach.

To really understand pricing, you must begin from fundamentals like the customer’s willingness to pay, the value captured by the company, and the value created for the customer. These basics are shown in the diagram below:

This might seem simple enough, but the exact level at which prices are ultimately set is determined by a whole host of factors, including product availability, market trends, and the need to maintain a competitive position within the market. In particular, if we are changing the price of an existing product, we must consider how the price elasticity of demand might cause sales to fluctuate.

Our four-step method for pricing starts from establishing the customer’s next best alternative, calculating the value added by our own product, and working from there. A summary of this method is given, along with an overview of pricing in general, in our article on the subject . However, the most complete resource is our pricing lesson in the MCC Academy .

3.3.4. Valuation

Valuation is fundamental to any kind of investment. Before allocating capital towards a particular opportunity, an investor must understand precisely what value it holds and how this compares to the other available options.

In short, valuation tells us how much we should be willing to pay to acquire a company or an asset.

There are many ways to value an asset - indeed the finer points are still subject to research in both the academic and private sectors.

Standard ways to assign value include asset-based valuations (notably the Net Asset Value or NAV) and the various multiples so widely used by market traders.

However, in consulting case interviews, you will only usually need to be familiar with Net Present Value (NPV) . This means you need to learn and master the NPV equation:

CF = Cash Flow r = Discount Rate

Whilst this is a pretty simple equation on the face of it, in order to make proper use of it, you will also need to develop a feel for interest/discount rates appropriate to different cases. This will be essential, as you will often have to estimate rational values for these rates for different investments before plugging those values into the NPV equation. Our Case Academy course has more detail here.

Note, though, that NPV is only really half the story.

NPV provides a kind of “absolute” value for an asset. However, the fact is that the worth of any asset will be different for different buyers , depending largely upon what the buyer already owns. In just the same way a spare clutch for a 1975 Ford will be a lot less valuable to a cyclist than to someone restoring the relevant classic car, so a courier business will be more valuable to an online retailer than to an airline.

As such, what we call the Total Enterprise Value (TEV) of an asset is calculated as a function of that asset’s NPV and of the potential cost and revenue synergies resulting from an acquisition. This is shown in the useful structure below:

You can learn more about all aspects of valuation in our article here , as well as in our dedicated video lesson in MCC Academy . These include guides to the kind of interest rates typically required to finance different kinds of investment.

3.3.5. Competitive Interactions

Most of what we’ve discussed so far in terms of case themes and our building block approach to them will all depend upon the prevailing competitive landscape our client exists within. Product prices, profit levels and ultimately valuations can all change over time in response to competition.

What is more, the zero sum dynamics of competitive interactions mean that these things can change quickly .

Companies enjoying near monopolies for years or even decades can quickly see their values go to zero, or near enough, in the face of some innovation by a competitor coming onto the market.

Nokia and Kodak thoroughly dominated the mobile phone and photography markets respectively - until new companies with new products pulled the rug out from under them and led to precipitous collapses.

New market entrants or old competitors with new ideas can throw a company’s whole business model up in the air overnight . Complex decisions about profound changes need to be made yesterday. Firms trying to save themselves will often slash prices in attempts to maintain sales - though this can actually make things worse and result in a corporate death-spiral. Consultants are then frequently called in to help companies survive - with this type of engagement carrying over to inform case interview questions.

You are running an airline and a low-cost competitor, like Ryanair, decides to start operating on your routes. You are rapidly losing customers to their lower fares. How do you respond?

Your eventual solutions to competitive interaction problems will likely need to be novel and unique to the situation. However, the process by which we understand competitive interactions and move towards those solutions is usually very methodical, moving through the limited dimensions in which a company can take action.

The following structure neatly encodes the general options open to responding to new sources of competition:

Of course, we would never suggest that you blanket-apply any strict, inflexible methodology to a whole swathe of case questions – this is precisely the approach that causes so much trouble for candidates using old-fashioned frameworks.

This structure is only a starting point - a shortcut to a bespoke framework specific to the case question in hand. You might well have to alter the details of the structure shown and you will almost certainly have to expand it as you lead the analysis . How you build out your structure and the solutions you provide are necessarily going to depend upon the specific details of the case question.

Thus, in order to deal with competitive interactions, you will need to put in the time to understand how the different strategies available function - as well as how competitors might then react to implementing such strategies. With enough practice, though, soon you won’t be fazed by even the most complex cases of competition between firms.

You can learn more in our article here and in our dedicated video lesson on competitive interaction in the MCC Academy case interview course.

3.4. Mental mathematics

Almost every interview case study will feature some mental mathematics and this is an area where many many candidates let themselves down.

As such, it makes sense to out in the time and make sure you are fully proficient.

Nothing beyond high school level is required, but you probably don’t do much mental arithmetic day to day and will likely need to practice quite a lot to get good enough to reliably perform at pace, under pressure.

We give a high-level overview of what you need to know in our consulting math article , but devote a whole section of our MCC Academy course to a deep dive on consulting math, with plenty of practice material to get you up to scratch.

4. How do I practice for case interviews?

As we said above - case interviews are much like chess. The rules are relatively quick to learn, but you need to practice a lot to get good.

If you’re working through our MCC Academy course, we recommend getting through the core Problem Driven Structure section. After that, you should be practising alongside working through the remainder of the course and beyond. However you do things, you need to get up to speed with the fundamentals before practice is going to do much more than confuse you.

Of course, if you’re enrolled in one of our mentoring programmes , your mentor will let you know precisely when and how you should be scheduling practice, as well as tracking your progress throughout.

4.1. Solo Practice

For solitary preparation, one of the best uses of your time is to work on your mental mathematics . This skill is neglected by many applicants - much to their immediate regret in the case interview. Find our mental math tool here or in our course, and practice at least ten minutes per day, from day one until the day before the interview.

Once you've covered our Building Blocks section, you should then start working through the cases in My Consulting Coach's case bank alongside your work on the course. This is a large library of case interview questions and answers in different formats and difficulties.

To build your confidence, start out on easier case questions, work through with the solutions, and don't worry about time. As you get better, you can move on to more difficult cases and try to get through them more quickly. You should practice around eight case studies on your own to build your confidence.

4.2. Peer practice

One you have worked through eight cases solo, you should be ready to simulate the interview more closely and start working with another person.

Here, many candidates turn to peer practice - that is, doing mock case interviews with friends, classmates or others also applying to consulting.

If you’re in university, and especially in business school, there will very likely be a consulting club for you to join and do lots of case practice with. If you don’t have anyone to practice, though, or if you just want to get a bit more volume in with others, our free meeting board lets you find fellow applicants from around the world with whom to practice.

4.3. Professional practice

You can do a lot practising by yourself and with peers. However, nothing will bring up your skills so quickly and profoundly as working with a real consultant.

Perhaps think about it like boxing. You can practice drills and work on punch bags all you want, but at some point you need to get into the ring and do some actual sparring if you ever want to be ready to fight.

Of course, it isn’t possible to secure the time of experienced top-tier consultants for free. However, when considering whether you should invest to boost your chances of success, it is worth considering the difference in your salary over even a just few years between getting into a top-tier firm versus a second-tier one. In the light of thousands in increased annual earnings (easily accumulating into millions over multiple years), it becomes clear that getting expert interview help really is one of the best investments you can make in your own future.

Should you decide to make this step, MyConsultingCoach can help, offering the highest quality case interview coaching service available . Each MCC case coach is selected as an MBB consultant with two or more years of experience and strong coaching expertise.

Case interview coaching is hugely beneficial in itself. However, for those who want to genuinely maximise their chances of securing a job offer - and especially for time-poor, busy professionals or hard-pressed students who want to take the guesswork and wasted time out of their case interview prep - we also offer a much more comprehensive service .

With one of our bespoke mentoring programmes , you are paired with a 5+ year experienced, ex-MBB mentor of your choosing, who will then oversee your whole case interview preparation from start to finish - giving you your best possible chance of landing a job!

4.4. Practice for online cases

Standard preparation for interview case studies will carry directly over to online cases.

However, if you want to do some more specific prep, you can work through cases solo to a timer and using a calculator and/or Excel (online cases generally allow calculators and second computers to help you, whilst these are banned in live case interviews).

Older PST-style questions also make great prep, but a particularly good simulation is the self-assessment tests included in our Case Academy course . These multiple choice business questions conducted with a strict time limit are great preparation for the current crop of online cases.

5. Fit interviews

As we’ve noted, even something billed as a case interview is very likely to contain a fit interview as a subset.

We have an article on fit interviews and also include a full set of lessons on how to answer fit questions properly as a subset of our comprehensive Case Academy course .

Here though, the important thing to convey is that you take preparing for fit questions every bit as seriously as you do case prep.

Since they sound the same as you might encounter when interviewing for other industries, the temptation is to regard these as “just normal interview questions”.

However, consulting firms take your answers to these questions a good deal more seriously than elsewhere.

This isn’t just for fluffy “corporate culture” reasons. The long hours and close teamwork, as well as the client-facing nature of management consulting, mean that your personality and ability to get on with others is going to be a big part of making you a tolerable and effective co-worker.

If you know you’ll have to spend 14+ hour working days with someone you hire and that your annual bonus depends on them not alienating clients, you better believe you’ll pay attention to their character in interview.

There are also hard-nosed financial reasons for the likes of McKinsey, Bain and BCG to drill down so hard on your answers.

In particular, top consultancies have huge issues with staff retention. The average management consultant only stays with these firms for around two years before they have moved on to a new industry.

In some cases, consultants bail out because they can’t keep up with the arduous consulting lifestyle of long hours and endless travel. In many instances, though, departing consultants are lured away by exit opportunities - such as the well trodden paths towards internal strategy roles, private equity or becoming a start-up founder.

Indeed, many individuals will intentionally use a two year stint in consulting as something like an MBA they are getting paid for - giving them accelerated exposure to the business world and letting them pivot into something new.

Consulting firms want to get a decent return on investment for training new recruits. Thus, they want hires who not only intend to stick with consulting longer-term, but also have a temperament that makes this feasible and an overall career trajectory where it just makes sense for them to stay put.

This should hammer home the point that, if you want to get an offer, you need to be fully prepared to answer fit questions - and to do so excellently - any time you have a case interview.

6. Interview day - what to expect, with tips

Of course, all this theory is well and good, but a lot of readers might be concerned about what exactly to expect in real life . It’s perfectly reasonable to want to get as clear a picture as possible here - we all want to know what we are going up against when we face a new challenge!

Indeed, it is important to think about your interview in more holistic terms, rather than just focusing on small aspects of analysis. Getting everything exactly correct is less important than the overall approach you take to reasoning and how you communicate - and candidates often lose sight of this fact.

In this section, then, we’ll run through the case interview experience from start to finish, directing you to resources with more details where appropriate. As a supplement to this, the following video from Bain is excellent. It portrays an abridged version of a case interview, but is very useful as a guide to what to expect - not just from Bain, but from McKinsey, BCG and any other high-level consulting firm.

6.1. Getting started

Though you might be shown through to the office by a staff member, usually your interviewer will come and collect you from a waiting area. Either way, when you first encounter them, you should greet your interviewer with a warm smile and a handshake (unless they do not offer their hand). Be confident without verging into arrogance. You will be asked to take a seat in the interviewer’s office, where the interview can then begin.

6.1.1. First impressions

In reality, your assessment begins before you even sit down at your interviewer’s desk. Whether at a conscious level or not, the impression you make within the first few seconds of meeting your interviewer is likely to significantly inform the final hiring decision (again, whether consciously or not).

Your presentation and how you hold yourself and behave are all important. If this seems strange, consider that, if hired, you will be personally responsible for many clients’ impressions of the firm. These things are part of the job! Much of material on the fit interview is useful here, whilst we also cover first impressions and presentation generally in our article on what to wear to interview .

As we have noted above, your interview might start with a fit segment - that is, with the interviewer asking questions about your experiences, your soft skills, and motivation to want to join consulting generally and that firm in particular. In short, the kinds of things a case study can’t tell them about you. We have a fit interview article and course to get you up to speed here.

6.1.2. Down to business

Following an initial conversation, your interviewer will introduce your case study , providing a prompt for the question you have to answer. You will have a pen and paper in front of you and should (neatly) note down the salient pieces of information (keep this up throughout the interview).

It is crucial here that you don’t delve into analysis or calculations straight away . Case prompts can be tricky and easy to misunderstand, especially when you are under pressure. Rather, ask any questions you need to fully understand the case question and then validate that understanding with the interviewer before you kick off any analysis. Better to eliminate mistakes now than experience that sinking feeling of realising you have gotten the whole thing wrong halfway through your case!

This process is covered in our article on identifying the problem and in greater detail in our Case Academy lesson on that subject.

6.1.3. Analysis

Once you understand the problem, you should take a few seconds to set your thoughts in order and draw up an initial structure for how you want to proceed. You might benefit from utilising one or more of our building blocks here to make a strong start. Present this to your interviewer and get their approval before you get into the nuts and bolts of analysis.

We cover the mechanics of how to structure your problem and lead the analysis in our articles here and here and more thoroughly in the MCC Case Academy . What it is important to convey here, though, is that your case interview is supposed to be a conversation rather than a written exam . Your interviewer takes a role closer to a co-worker than an invigilator and you should be conversing with them throughout.

Indeed, how you communicate with your interviewer and explain your rationale is a crucial element of how you will be assessed. Case questions in general, are not posed to see if you can produce the correct answer, but rather to see how you think . Your interviewer wants to see you approach the case in a structured, rational fashion. The only way they are going to know your thought processes, though, is if you tell them!

To demonstrate this point, here is another excellent video from Bain, where candidates are compared.

Note that multiple different answers to each question are considered acceptable and that Bain is primarily concerned with the thought processes of the candidate’s exhibit .

Another reason why communication is absolutely essential to case interview success is the simple reason that you will not have all the facts you need to complete your analysis at the outset. Rather, you will usually have to ask the interviewer for additional data throughout the case to allow you to proceed .

NB: Don't be let down by your math!

Your ability to quickly and accurately interpret these charts and other figures under pressure is one of the skills that is being assessed. You will also need to make any calculations with the same speed and accuracy (without a calculator!). As such, be sure that you are up to speed on your consulting math .

6.1.4. Recommendation

Finally, you will be asked to present a recommendation. This should be delivered in a brief, top-down "elevator pitch" format , as if you are speaking to a time-pressured CEO. Again here, how you communicate will be just as important as the details of what you say, and you should aim to speak clearly and with confidence.

For more detail on how to give the perfect recommendation, take a look at our articles on the Pyramid Principle and providing recommendations , as well the relevant lesson within MCC Academy .

6.1.5. Wrapping up

After your case is complete, there might be a few more fit questions - including a chance for you to ask some questions of the interviewer . This is your opportunity to make a good parting impression.

We deal with the details in our fit interview resources. However, it is always worth bearing in mind just how many candidates your interviewers are going to see giving similar answers to the same questions in the same office. A pretty obvious pre-requisite to being considered for a job is that your interviewer remembers you in the first place. Whilst you shouldn't do something stupid just to be noticed, asking interesting parting questions is a good way to be remembered.

Now, with the interview wrapped up, it’s time to shake hands, thank the interviewer for their time and leave the room .

You might have other interviews or tests that day or you might be heading home. Either way, if know that you did all you could to prepare, you can leave content in the knowledge that you have the best possible chance of receiving an email with a job offer. This is our mission at MCC - to provide all the resources you need to realise your full potential and land your dream consulting job!

6.2. Remote and one-way interview tips

Zoom case interviews and “one-way” automated fit interviews are becoming more common as selection processes are increasingly remote, with these new formats being accompanied by their own unique challenges.

Obviously you won’t have to worry about lobbies and shaking hands for a video interview. However, a lot remains the same. You still need to do the same prep in terms of getting good at case cracking and expressing your fit answers. The specific considerations around remote interviews are, in effect, around making sure you come across as effectively as you would in person.

6.2.1. Connection

It sounds trivial, but a successful video interview of any kind presupposes a functioning computer with a stable and sufficient internet connection.

Absolutely don’t forget to have your laptop plugged in, as your battery will definitely let you down mid-interview. Similarly, make sure any housemates or family know not to use the microwave, vacuum cleaner or anything else that makes wifi cut out (or makes a lot of noise, obviously)

If you have to connect on a platform you don’t use much (for example, if it’s on Teams and you’re used to Zoom), make sure you have the up to date version of the app in advance, rather than having to wait for an obligatory download and end up late to join. Whilst you’re at it, make sure you’re familiar with the controls etc. At the risk of being made fun of, don’t be afraid to have a practice call with a friend.

6.2.2. Dress

You might get guidance on a slightly more relaxed dress code for a Zoom interview. However, if in doubt, dress as you would for the real thing (see our article here ).

Either way, always remember that presentation is part of what you are being assessed on - the firm needs to know you can be presentable for clients. Taking this stuff seriously also shows respect for your interviewer and their time in interviewing you.

6.2.3. Lighting

An aspect of presentation that you have to devote some thought to for a Zoom interview is your lighting.

Hopefully, you long ago nailed a lighting set-up during the Covid lockdowns. However, make sure to check your lighting in advance with your webcam - bearing in mind what time if day your interview actually is. If your interview is late afternoon, don’t just check in the morning. Make sure you aren’t going to be blinded from light coming in a window behind your screen, or that you end up with the weird shadow stripes from blinds all over your face.

Natural light is always best, but if there won’t be much of that during your interview, you’ll likely want to experiment with moving some lamps around.

6.2.4. Clarity

The actual stories you tell in an automated “one-way” fit interview will be the same as for a live equivalent. If anything, things should be easier, as you can rattle off a practised monologue without an interviewer interrupting you to ask for clarifications.

You can probably also assume that the algorithm assessing your performance is sufficiently capable that it will be observing you at much the same level as a human interviewer. However, it is probably still worth speaking as clearly as possible with these kinds of interviews and paying extra attention to your lighting to ensure that your face is clearly visible.

No doubt the AIs scoring these interviews are improving all the time, but you still want to make their job as easy as possible. Just think about the same things as you would with a live Zoom interview, but more so.

7. How we can help

There are lots of great free resources on this site to get you started with preparation, from all our articles on case solving and consulting skills to our free case library and peer practice meeting board .

To step your preparation up a notch, though, our Case Academy course will give you everything you need to know to solve the most complex of cases - whether those are in live interviews, with chatbots, written tests or any other format.

Whatever kind of case you end up facing, nothing will bring up your skillset faster than the kind of acute, actionable feedback you can get from a mock case interview a real, MBB consultant. Whilst it's possible to get by without this kind of coaching, it does tend to be the biggest single difference maker for successful candidates.

Secrets to a successful case-study interview

January 9, 2023

Prepping for (and maybe fretting) the case-study interview?

While this kind of interview may appear intimidating, consider this: The interviewer really wants you to do well.

So, shake off the nerves, relax and have fun.

Tips for standing out in the case-study interview: 

• Take your time; don't rush it.  Talk through the problem. If you can't make sense of it, take a moment and allow yourself some time to process what you've been missing. If you get stuck, get creative. Don't let yourself get bogged down; rely on your ingenuity. 
• Ask questions.  You can always ask your interviewer to define an acronym or to repeat or confirm details. If the interviewer asks, “How do we achieve success?”, don’t be afraid to ask, “What does ‘success’ mean to you? Is it turning a profit? Raising the company’s profile?” When you work on a client project, you need to ask questions to figure out what the problems might be, and the same applies here. The interviewer is your biggest asset in the room. They have the information you need to “solve the case” successfully. Use them wisely!
• Be flexible.  The focus of a case-study interview may vary. So, be prepared to participate in whatever discussion the interviewer has in mind. They may spend the first half of the interview asking about your previous experience, or they may dive right into the case study at the start. The bottom line: Be flexible, and be ready to discuss the work you do and how you do it.
• Use visual aids.  Don’t be afraid to use pen and paper, sketch out your thoughts, and talk through the problem at hand if it helps you get your ideas across. What matters most is demonstrating that you can solve problems.
• Focus on impact.  Inventory the information you have, and then dive in where you can have the most impact. Don’t forget to discuss your thought process and explain your assumptions.
• Tell a story.  Your experience has helped you progress in your career and education; use that experience. For example, in a business case study, you could bring your experience as a traveler to a case about a hypothetical airline. Your individuality is important. Your unique insights will serve you well when you’re interviewing.
• Pay attention to cues.  If the interviewer says something, it probably means something. Don’t dismiss seemingly extraneous details. For example, the interviewer might say, “The case is about a retailer who wants to increase the value of a company it purchased, and the owner loved the brand when growing up.” The purpose of that detail is to indicate that turning around and selling the asset is not an option for making it profitable, because the owner is attached to it.

Preparing for the job you want can take time, but it’s a worthwhile investment—especially when you receive an offer.

Your ideas, ingenuity and determination make a difference.

How to Conduct a High-Value Case Study Interview (And 4 Mistakes To Avoid)

Let’s talk about case study interviews.

Case studies allow brands to demonstrate exactly how they can help resolve specific pain points, how customers are using their products or tools, and an exact example of what kind of results people can expect. 

This is important because plenty of businesses make big claims, trying to outshine their competition. There isn’t a marketing agency out there that won’t promise to get you more reach or a law firm that doesn’t like to appear confident in their ability to win cases.

Every brand will proclaim that they can best solve their customer’s needs, but those claims on their own rarely mean much. They want to know that you can live up to what you promise, and seeing case studies from existing clients can win them over.

To create high-value case studies that can help you attract and convert customers, it only makes sense that you’ll need to start with a killer interview.

In this post, we’re going to look at how to conduct a case study interview that will help you create high-value case studies to draw attention and quality leads to your business.

Why Interviewing Clients Directly for Case Studies Is So Important 

We’re all busy, so it can be tempting to put off case studies or relegate the case study interviews to a quick Google form that asks specific questions.

While you can create basic case studies off of this information, especially if you only want to showcase quick results, it won’t be nearly as impactful as case studies created off of more in-depth interviews.

These interviews can take place by email, phone, Zoom, or in person, but the idea is that there is plenty of room for open discussion. Actual interviews can help you go beyond basic information so that you can get to the story and the pain points of how your clients have been impacted. 

There’s also a great chance that they’ll share more during an open conversation that can be a crucial component to the case study that they may not have thought to share on a form because you may not have thought to ask. 

Strong case study interviews are an essential part of creating dynamic, engaging content that can actually convince your target audience that you’re the right business to purchase from.

How to Prepare for Case Study Interviews 

Conducting a rocking case study interview all comes down to great preparation, so let’s take a look at how to do exactly this. 

Think About Your Target Audience’s Pain Points 

Before you start formulating your case study interview questions, you want to think about what you want your case studies to convey. 

Case studies allow you to go beyond sharing simple results (which are powerful enough on their own and should still be an important part of the content), allowing you to dive into more nuance to address the pain points of potential leads fully. 

For example, a virtual phone line company may want to consider going beyond stressing their 99% service uptimes and touch on additional features they offer. Emphasizing that offer call scheduling to give business owners more of their time back on an automated basis, for example. 

This case study from AdEspresso is an excellent example of what to look at when considering your audience’s pain points. There’s a client who ran highly seasonal campaigns who didn’t want to leverage discounts to drive sales to keep it fair for pre-order customers. It discusses her specific challenges and pain points and addresses the overall solution instead of simply listing results. 

As pain points can be a crucial part of writing compelling case studies , break down your audience’s niches and different needs that they may have. You can ask your interviewee questions that can help you tap into the pain points for the case study. We’ll look at specific questions for how to tackle this in a moment.

Expect Interviewee Objections 

When you first reach out to a potential case study subject and start discussing the idea of featuring their brand, know that you may encounter objections from the subject themselves.

They may be alright with you using some part of their story, strategy, or results while still being concerned about protecting their own or their business’s privacy. 

As a content marketer, for example, I know exactly how many of my posts are performing across some of my client sites, how much they drive in revenue, how much traffic they’re getting, and what’s bringing them there. 

A client may be okay with me talking about working with them or sharing samples but might be less than thrilled about me divulging information about their specific site pattern trends, the custom-for-them strategy we used, or their revenue. For example, the case study from SEMRush below is extremel y specific; not all clients may be comfortable with this.

Be prepared for this before you reach out, and consider what you can do to accommodate requests. These objections may arise before the case study interview, but they may pop up during as well.

Here are a few examples of common workarounds: 

• Instead of saying that my post for Bob’s Blog helped the site go from $100 in revenue to $200, I can say that it doubled the revenue or doubled conversion rates (whatever is accurate).
• Maybe I can share the general strategy I used for Bob’s blog without actually naming them and omitting key identifying details, like the keywords used. 
• They may be alright with you sharing the detailed strategy and general results (2x conversion rate instead of 5.6% conversion rate) and the brand name , OR they may only be okay with sharing their story and results. 

Each client is different and comfortable with sharing different information. While it is typically most beneficial to be able to name the client’s brand name, if this isn’t an option consider settling for a more specific industry tag like “a client in the women’s sustainable fashion industry” instead.

Watch what our customers say

Christie Horsman, VP of Marketing, Thinkific

Ready Your Case Study Interview Questions 

After you’ve thought about potential objections and any key notes you really want to focus on with your case study, you can put together your case study interview questions.

We’ll discuss specific case study interview questions and templates a bit later on, but prepare these in advance. Ideally, research each individual case study subject in advance and try to ask questions that will be relevant to them. 

This is important- write your questions down, even if you’ll be having a phone call. Organize them with the natural progression you expect the call or conversation to take so you don’t lose your train of thought, and check back before the call is over to make sure you’ve asked everything you need to.

At the end of the interview, ask if there’s anything else they’d like to share. Don’t forget this: some of the best parts of case studies can surprise the interviewer at the time!

Look for a Story 

When you’re putting together your questions and interviewing the case study subject, keep your eyes open for a “story.” 

Stories don’t have to be long and complex; they should center your brand whenever possible. 

If your automation software helps a business owner save time, that’s an appealing benefit. But if they’re happy to share that it meant that they could put more time into expanding their business or that they could be at home more with their newborn child, that takes a simple fact and makes it more emotionally compelling. 

You can build an entire case study around a great story, and you can see exactly how effective this is with the headline of this case study from Freshbooks , reading “How Freshbooks Helped Marc Keep His New Year’s Resolution.

4 Case Study Interview Mistakes to Avoid

When you’re preparing for and conducting case study interviews, there are a few common mistakes that you’ll want to avoid. These can cause you to miss out on potential interviews or lessen the impact of the interviews themselves.

Make sure to avoid the following mistakes:

• Using a single form that’s emailed to case study subjects. Whenever possible, back-and-forth conversations can typically yield much more dynamic case studies. While some clients may firmly want to stick to email, try to opt for zoom calls or at least several emails if you can. 
• Not being clear on what information you can use in the case study. Make sure they know that you’ll publish it on your site, and get their permission in writing (email is fine!) to feature them and their results. It’s considered a good practice to let the client review the case study before you publish it if they’re concerned. 
• Trying to shoehorn a client into a predetermined story. I once worked with another content writer on a case study project, and during the interview, it was so clear they were trying to fit a subject’s experience into this perfect story the writer had concocted. This typically doesn’t work, however, and it can prevent you from finding the great and unique parts of each individual’s story and success. Go in with an open mind if you can. 
• Skipping small talk. If you go in all-business, the case study subject may be more likely to answer only what’s asked. When you start on the basis of enjoying the conversation, however, they’ll share more, and that can be where the magic happens.

Case Study Interview Examples: What This May Look Like 

Need a case study interview template with plenty of questions to draw inspiration from? What you ask will vary depending on your industry, your client, and the type of case study you want to create, but there are some set questions you should ask across the board.

It’s good to break these down into different sections while asking open-ended questions so that there’s plenty of room for the subject to share more. 

Start by asking about the brand with questions like the following:

• “Can you tell me about your brand and what you do?”
• “Is there anything you’d like us to make sure our readers know about your brand?”

Then move on to asking about how they use the product and their challenges. Some case study interview questions for this may include:

• “Why did you decide to use our brand/product/service? What feature made you choose us?”
• “What pain points and challenges did you have before coming to us?”
• “Have you tried other solutions before? If so, why did you decide to come to us?”

Next, focus on process and results:

• “Can you tell us how you’ve used our product/service and how it’s helped your business?”
• “What results did you get? Did it speed up your team/improve efficiency/drive more results/improve health/ insert use case here?”
• How long were you able to maintain these results, and how did the results help you?

Final Thoughts 

A case study interview can seem like a daunting task, but with a little bit of research ahead of time, it can be a smooth process that can yield exceptional information for outstanding case studies. Remember that case studies can only be as strong as the information you have, so the importance of a great interview can’t be overstated.

For best results, take a look at a few case studies online that you liked as a customer, and think about what you’d need to ask in order to get that information. That can help you cover your bases and ensure that you’re asking everything you need to.

A Comprehensive Guide to Case Interview Prep [tips updated 2024]

• Last Updated March, 2024

Rebecca Smith-Allen

Former McKinsey Engagement Manager

What Are the Best Ways to Prepare for Interviews with Management Consulting Firms?

Congratulations!

If you’re on this page, you’re probably considering a career in management consulting or are already in the middle of the interview process.

We’re here to help.

We’re a team of more than 20 former McKinsey, Bain, and BCG consultants and recruiters (our average time in consulting is 13 years each) and we put together this guide to help you prepare for getting your consulting offer.

After reading this, we hope “congratulations” is also what you’ll hear when you leave your final interviews.

Management Consulting Jobs Are in High Demand

Management consulting jobs are among the most sought-after positions in on-campus recruiting, whether you’re applying as an undergraduate or from a business school. 

Consulting firm recruits also include law school students, Ph.D. program candidates and people who’ve already started their professional careers in other industries.

Management consulting firms are filled with smart, driven people working to solve hard business problems. 

This work is a great launching pad for your career. 

Top consultancies offer competitive salaries and also invest significantly in employee development. A job at a management consulting firm will expose you to multiple different industries and types of business problems. 

There’s a lot to like about a career in consulting!

Competition for Jobs with Top Consulting Firms Is Fierce, so Preparation Is Essential.

But attractive jobs are usually highly competitive, and that’s definitely the case in management consulting. 

Top firms typically make offers to only about 1% of the people who apply. It’s not impossible to get a job with firms like McKinsey, Bain, and BCG (also known as the MBB firms), but it requires preparation.

In particular, successful candidates know that consulting firms use a particular type of interview question — the case study interview — and they know what recruiters are looking for in answers. 

In this article, we’ll help you prepare for management consulting interviews by answering the following questions:

• What is a case interview?
• How do I answer a case question?
• What is the best approach for case interview prep?

We’ll also provide tips and tricks that will help you to ace your case.  

Whether you’re aiming for a job at one of the MBB firms (McKinsey, Bain, or BCG), with other consultancies such as AT Kearney, L.E.K. or Oliver Wyman, or with the consulting arms of the large accounting firms such as Deloitte, Accenture, PwC, Ernst & Young, or KPMG, we can help you get there.  

What Is a Consulting Case Study Interview (also known as the “Case Interview”)?

A Case Study Interview is a real-time problem-solving test used to screen candidates for their ability to succeed in consulting. 

The case is presented as an open-ended question, often a problem that a specific type of business is facing, that an interviewer asks a candidate to solve.

Sample Case Interview Questions

Sales of drinks in Coffee Bean cafes are decreasing. What is causing the sales decrease?

Turnover of store employees at Burgers R’ Us restaurants has increased over prior years. What would you advise the company to do?

Donations to Caring Hands are decreasing, straining the non-profit’s ability to help the families it targets. What should the organization do to turn this around?

Case Interview 101 – The Basics for Beginners

You don’t need an MBA or an undergraduate degree in economics to land a job in consulting. But you will need to learn some business basics to be able to crack case interviews.

This section covers the concepts non-business students need to become familiar with, such as:

• The income statement – an overview
• Common formulas used in case interviews
• Business concepts you need to know
• Common types of case interviews

Case Interview 101, Part 1: The Income Statement

To solve cases, you first need to understand broadly how companies make money. For any specific case, you’ll want to make sure you understand how that company makes money. 

The most common way companies make money is by selling a product or service for more than it costs to produce, thereby earning a profit . 

Companies use three major financial statements to monitor and report their financial performance: 

(1) The income statement (2) The balance sheet (3) The cash flow statement 

An income statement (or profit and loss statement or statement of revenue and expenses) is a record of a company’s profit or loss over a specific period of time . The profit or loss is calculated by taking the revenues generated and subtracting the expenses incurred over the same period of time. The income statement has 3 major categories: Revenue, Expenses, and Profit or Loss .

Revenue is the total amount of money generated by a company from selling its products or services. It is also referred to as gross sales or “top line” as it sits at the top of the income statement. 

Costs are expenses incurred by a company to make its products or services. In the income statement there are three types of costs: 

• Costs of goods sold (COGS) or cost of sales are the direct costs of making products or providing a service. For a burger restaurant, for example, the COGS would include things like the meat, bun, and hourly labor of cooks, cashiers, and shift supervisors.
• Operating expenses are costs that are indirectly tied to the making of products or services. These include selling, general, and administrative (SGA) expenses, management salaries, depreciation, and amortization. Depreciation and amortization are non-cash expenses that reflect the value of big assets like machinery or buildings going down over time. For example, if our burger restaurant buys a grill to cook burgers on for $1,000 and expects it to last for 10 years, it would spread out the cost over that period, $100 per year. Other operating expenses for our burger restaurant would include things like advertising, the rent on the company’s headquarters, and the salary of the CEO.
• Costs incurred from non-operating activities such as interest paid on loans. These costs are rarely part of case interviews.

Profit or Loss :

Income statements generally show 3 levels of profit (loss) or earnings: Gross Profit; Earnings Before Interest, Tax, Depreciation and Amortization (EBITDA); and Net Profit.

Gross profit or loss

This is calculated by subtracting COGS or the cost of sales from the total revenue generated. If the costs are higher than the revenue generated, then the company has made a loss.

EBITDA and EBIT

EBITDA is calculated by subtracting operating expenses from the gross profit. EBIT is calculated by subtracting depreciation and amortization from EBITDA. 

As mentioned above, depreciation and amortization are non-cash expenses. So if the amount of cash generated by selling a product or service is important to your analysis, you should look at EBITDA. If looking at a more fully loaded cost is the focus of your analysis, use EBIT.

Net Profit or Loss

This is calculated by subtracting interest and tax from EBIT. It is also known as Net Income and refers to the profit (or loss) for the period. This is also known as the “bottom line” as it sits at the bottom of the income statement. This is the ultimate measure of whether a company’s activities are profitable during a certain time period when all costs are considered.  

Case Interview 101, Part 2: Common Formulas Used in Case Interviews

Here is a look at common formulas used in case interviews.

Profitability formula:

The profitability formula is used in profit (or loss) related cases. The profit or loss can be calculated using the following formula:

             Profit (or Loss) = Revenue – Costs

As mentioned above:

• Revenue is the money generated from selling a product or service. It can be broken down into price per unit and number of units sold . 
• Costs are the expenses incurred to make the product or service and can be broken down into cost per unit and number of units sold . 

The formula can further be broken down into:

            Profit (or Loss) = (price per unit x number of units sold) – (cost per unit x number of units sold)

There are other ways to break down revenue and cost depending on the case question.

• Revenue can be broken down by product or service line, customer type, or geographic region (e.g., North American, Europe, Asia)
• Costs can be broken into fixed costs and variable costs, or components such as overhead, salary, etc.

It is often helpful to break costs down into fixed and variable to solve consulting cases, and understanding the difference is important. Fixed costs, like rent for a store or the cost of equipment, are incurred regardless of how many units a company sells; whereas variable costs are only incurred with the production of each additional unit. Because of this, it can be helpful to sell incremental units even at a loss for a short period of time if it helps cover fixed costs.

So the profitability formula can also be written as:

            Profit (or Loss) = (price per unit x number of units sold) – (fixed + variable costs)

P rofitability example:

Your client, a manufacturer, is facing a decline in profits. Your client wants your help solving this problem. We’ll use this example to demonstrate all the formulas in this section.

The first step you could take is to calculate the past year’s profit given the following information:

• Number of units sold = 1 million
• Price per unit = $10
• Cost per unit = $8

          Profit (or Loss) = ($10 x 1 million) – ($8 x 1 million)

          Profit = $2 million

Profit margin formula:

Profit margin indicates how many cents of profit the company generated for each dollar of sale. It’s typically used to measure the financial health of a company . You can compare the profit margin of a company against its historical margins to evaluate whether its current performance is better or worse than past performance. You can also compare it against companies in the same industry to evaluate whether its financial performance is stronger or weaker.

Profit margin can be calculated using the formula:

          Profit margin = (Profit / Revenue ) *100%

Profit margin example:

To calculate the profit margin, first, you need to calculate company revenues as follows:

            Revenue = 1 million x $10

           Revenue = $ 10 million

You can now calculate the profit margin as follows:

            Profit margin = ($2 million / $10 million) x 100%

           Profit margin = 20%

Note you can combine both the formulas for faster calculation.

Market share formula:

Market share is the size of the company in relation to the size of the industry in which it operates, where size is typically measured in annual revenues. It is used to compare the size of a company to its competitors and the industry as a whole. It can be used in market entry cases because industries with a lot of small competitors are generally easier to enter than ones with only a few big competitors. It’s also used in profitability cases because, in general, companies with a large market share also have more market power to do things like set prices.

Market share can be calculated using the following formula:

            Market share (%) =total company revenue / total industry revenue  

Market share example:

Using the example from above, say you decide to determine the company’s market share as part of your analysis. In this example, the industry has annual revenues of $ 200 million.

            Market share (%) = $ 10 million / $ 200 million

           Market share = 5%

Growth Rate Formula:

This refers to the specific change of a variable within a specific period of time. Growth rates can be used in assessing the financial performance of a company over time. For example, high revenue growth rates would likely be a sign of strong financial performance. High cost growth rates may be a sign that a company is having financial trouble.

The growth rate is calculated using the formula:

            Growth rate (%) = (New – Old) / Old

Growth rate example:

To calculate the manufacturer’s revenue growth rate. Last year’s revenue was $ 9.5 million therefore the revenue growth rate is:

            Revenue growth rate = ($10 million – $9.5 million) / $9.5 million

            Revenue growth rate =5%

You can assess whether a company’s growth rate is strong by comparing it to other growth rates such as:

• The company’s growth in the prior year.
• The growth of the market or of competitors.
• The rate of inflation.

Mature companies are likely to see single-digit growth rates unless they launch a very successful new product or they acquire a company. On the other hand, startup investors typically expect double- or triple-digit annual growth during a company’s early years.

Return on investment formula:

Return on investment (ROI) is a profitability metric that indicates how well an investment performed (or will perform). It can be used to compare the profitability or efficiency of an investment or decide which of alternative investments to make. 

ROI is calculated using the following formula:

            ROI (%) = Profit / Cost of investment

ROI example:

Suppose our manufacturer mentions that they purchased state-of-the-art machinery to make their product. It cost $8 million. You decide to calculate the ROI on this investment. 

            ROI  = $2 million / $8 million

           ROI=25%

Break-even formula:

Break-even is the point at which the total revenue and total costs are equal, meaning there is no loss or profit at that point. Break-even is typically used to help companies determine the minimum number of units that need to be sold to cover all the costs used to produce those units. 

An executive might want to know that they could break even at 100,000 units sold because if she thought they could sell more than that, it would be profitable to enter the market. If she thought they’d sell less, they wouldn’t enter the market.

Break-even can be calculated using the following formula:

              Breakeven (units) = Fixed costs  / (sales price – variable cost per unit)

Break-even example:

If a product required a $50,000 investment in equipment (a fixed cost), sold for $5, and cost $4 per unit in variable costs, its breakeven would be: 

              Breakeven (units) = $50,000  / ($5 – $4)

              Breakeven= 50,000 units

Payback period formula:

Managers may also look at the payback period on an investment or, in other words, how long it would take to earn back the cash required to enter a new business. This investment could be a new piece of equipment or a marketing campaign needed to create customer awareness of a new product. This is a different way of looking at the same question that the breakeven formula asks: is it worth my while to make this investment?

The payback period can be calculated using the following formula:

              Payback (years) = Investment cost / annual profit

Payback years example:

Using the same example, you decided to calculate the payback years of the new state-of-art machinery

            Payback (years)= $8 million / $2 million

           Payback = 4 years

Capacity of equipment:

The capacity of equipment is the maximum output or units a piece of equipment can produce with the available resources over a set period of time.

Capacity can be calculated using the following formula:

            Capacity (units) =Total capacity / Capacity required to make one unit

Capacity example:

To calculate the capacity of our manufacturer’s machinery, we’d need to know that it can produce a unit every 10 minutes and that the client operates 12-hour shifts.

              Capacity (units) = 12 hours x (60 minutes per hour) / 10 minutes

             Capacity = 72 units / day

The utilization rate of equipment:

Utilization rate is the percent of available time the equipment or machinery is actually used. It measures efficiency and can be used by companies to make informed decisions on timelines and inventory, or whether additional equipment is needed.

The utilization rate of equipment can be calculated by the following formula:

              Utilization rate (%) =Actual output / Maximum output

Utilization rate example:

Using the same example, imagine that the management tells you that in a 12-hour shift, the machine produces 50 units and there are two 45-minute breaks.

First, you would need to calculate the potential output.

               Actual hours of operation = 12 hours – 1.5 hours = 10.5 hours

               Potential output = (10.5 hours / 12 hours) x 72 units

               Potential output = 63 units

Then, calculate the utilization rate.

                Utilization rate = 50 units / 63 units

                Utilization rate = 79%

Utilization rates raise interesting issues in a case. It raises questions such as:

• If potential output is 63 units, why are only 50 being produced (e.g., machine downtime, worker errors), and what can be done to solve these problems?
• Could the company stagger employee breaks to get potential output up to 72 units from 63?

Case Interview 101, Part 3: Business Concepts You Need to Know

Here are some common business concepts that you need to know as you prepare for your interview.

Process : This is a set of actions or operations that lead to results (products or services). This typically describes how a company makes its products or services. The steps can be performed by workers, equipment, or computers. In a case, this is mostly used in situations where a client would like to make their processes more efficient. For example, a client who is in logistics would like to reduce the cost of its operations by improving the efficiency of its processes, such as by reducing equipment downtime or scheduling deliveries according to time-saving routes. 

Best practices: Best practices are methods or techniques that are considered to be the working standards and guides in a given situation . In a business situation, best practices are used to benchmark companies against the standard and can serve as a roadmap on how to improve the efficiency of their operations.

Hypotheses: Tentative answers to a problem or an assumption based on some evidence. The hypothesis-driven approach is a common approach to solving problems in the consulting world because consultants don’t want to waste time fully researching all possible solutions. They want to move quickly to the most likely answer and then test whether it is or is not the best answer. This approach can be used to solve case interview questions where you first assume an answer to the case problem and check whether this is true or not through analysis. If it is not true, you revise your hypothesis.

Issue tree: This is a common approach in consulting used to solve complex problems . An issue tree is used to break down complex problems into key components in a structured manner. In a case interview, you can use the issue tree to break down the client’s problem into manageable chunks or to break down a formula such as the profitability formula into key components.

Read our article for more information on Issue Trees .

MECE: MECE stands for mutually exclusive and collectively exhaustive . It is a way of bucketing problems, ideas, or solutions with no overlapping between the buckets and with each item having a place in one bucket only (mutually exclusive), and with the buckets including all possible items relevant to the context (collectively exhaustive). In a case interview, you can use MECE with the issue tree when breaking down problems or when identifying solutions for the client. MECE issue trees are considered the gold standard for problem-solving so this concept is very good to know. 

You can also use the concept of MECE when segmenting a market – for example, if you are sizing a market and intend to lay out different purchasing behavior assumptions for different customer segments. For example:

Customer segment                         Purchase frequency for items from coffee shops

Women under 30                             4 times per week, purchase includes food item plus beverage Men under 30                                     2 times per week, purchase includes only beverage Women 31 and over                         4 times per month, purchase includes only beverage Men 31 and over                                 3 times per month, purchase includes only beverage

Note how in this example, everyone would fall into one customer segment and only one customer segment. Read our article for more about MECE problem-solving .

Root causes: This is the core issue or main reason for a problem . It is used in problem-solving to identify solutions that appropriately address the problem. The term root cause is used to distinguish between symptoms of a problem, which may be obvious, and the underlying issue that needs to be solved, which may not be obvious. For example, a decline in sales volume is a symptom. The root cause could be high prices, poor product quality, product unavailability, or any number of other issues. You can’t fix the symptom of declining sales volume until you identify the root cause behind the problem. 

In a case interview, you’ll need to identify possible causes of the client’s problem and then ask questions and do analysis to identify the root cause. Once you do, you can make the most appropriate recommendations for the client.

Break-even analysis: This is the calculation used to determine the point at which the total revenue and total costs are equal meaning there is no loss or profit. In business situations, it helps determine at which point the business, investment, or new product or service will become profitable. In case interviews, you can use the break-even analysis to determine whether a client should make a certain investment, say in machinery or a new product line, based on how likely it is that they’ll exceed the break-even threshold.

Case Interview 101, Part 4: Common Types of Case Interviews

In this section, we will review 4 common types of case interviews.

Market-sizing Questions

Market-sizing questions typically appear in cases where clients want to grow or expand their business such as market entry or profitability cases. The client either wants to understand the market size of the current business or of a potential new product line or geography or customer group to understand whether it is big enough to be interesting. 

Sample case questions

“How many cups of coffee does Starbucks sell in a day?” “Estimate the fleet size of Delta Airlines.” “Estimate market size for air-conditioners in New York.”  “Estimate market size for an anti-smoking pill in the U.S.”

You are not expected to know the exact answer to market-sizing questions. Instead, the interviewer wants to see that you can use simple math and logical deduction to build out an answer. For these questions, it is good to memorize a few facts that will help you make assumptions. For example, a good place to start is the population of the U.S. or the population of a U.S. city (or country and city that you live in). 

For more information and examples, read our article on Market-sizing Cases .

Revenue Growth Case Interviews

In revenue growth cases, the client typically wants to grow their business. This can be done by increasing revenue of the current product/service line, by adding a new product/service line, or by selling to a new type of customer or in a new geography. 

They could do this by building a new offering, buying another company, or partnering (joint venture) with another company that already offers what they want to sell. 

“A manufacturer sees its revenue stagnating. It wants to know whether raising price or selling more units is a better path to growing revenue, and how to pursue it.”

“A local theater house thinks there is an opportunity to expand their current offerings to the very loyal client base. What new product or service could they offer their customers? What would be the impact on revenue from expanding their offerings?”

“A regional fast-food chain, serving hamburgers and fries, is experiencing increasing demand outside of its main regions of operation and wants to expand. What regions would have the biggest impact on its revenue?”

You should remember that there are multiple ways to achieve revenue growth. One thing to consider is the client and industry context when tackling revenue growth questions. For example, does the client have a good market size in the industry? Does the client have the capability to offer new products/services? Is the industry highly competitive?

For more information, read our article on Revenue Growth Cases .

Market Entry Case Interviews

In market entry cases, the client wants to know if they can enter a market and be profitable. For example, entering a different geography, new demography, or new product/service line. (Note, there can be overlap between revenue growth cases and market entry cases.)

“A U.S.-based consumer electronics manufacturer is thinking of expanding into emerging markets. What is the potential revenue growth if they choose to expand into India?”

“A telecom operator is looking to diversify their presence in the U.S. and wants to enter the video streaming market. How can they capture a significant market share?”

“A renewable energy company that specializes in large equipment such as windmills wants to enter the retail market and sell smaller equipment directly to individual homes. They would like to know if this is a good idea.”

There are a number of frameworks you can build off of to tackle a market-entry case. For example, Porter’s Five Forces, Business Situation Framework or 3C&P (customer, competition, company, and product), and Supply & Demand among others. It is key to consider the “new” market context as well as the client context to enter this market. 

To find out more on this, read our article on The Market Entry Framework .

Cost Optimization Case Interviews

Cost optimization cases or questions can be part of a profitability case where a client is experiencing declining profitability or when a client wants to improve efficiency.

“A national hotel chain has seen its operational costs significantly increase over the last year and would like you to figure out why.”

“A juice manufacturer has been experiencing a steady increase in revenue over the past 5 years however their cost has been increasing at a faster rate, meaning the profits have not grown as expected. What is the root cause of the significant increase in cost?”

“A tour company would like to reduce their costs due to the falling number of tourists over the past few years. What ways would you recommend for them to reduce their costs?’

For cost optimization cases, remember to break down the cost components. For example, you can break them down into fixed and variable costs or cost of goods sold and operational costs and then brainstorm the categories of each that will likely apply to the company at hand. This will make it easier to identify what costs should be reduced or eliminated.

Check out Types of Case Interviews article for more detail on these types of cases and more.

Why Do Top Consulting Firms Use Case Interview Questions?

Management consultancies are not the only types of firms that use case interview questions to evaluate candidates. 

Investment banks, consumer marketing companies, and others use the case interview structure in their interview process.

Because case interviews show how a candidate would problem solve in real time. 

Solving complex, ambiguous problems is at the heart at what consultants do every day.

This type of interview question mimics the analytic process a consultant might go through in a 3-month project, but it does it in 30 minutes, the time allowed in a typical interview. 

The interviewer can probe whether a candidate’s approach is well-structured, creative, and displays good business sense.

How Do Consulting Recruiters Evaluate Candidates?

The main thing that recruiters are looking for in case study interviews is whether or not they’d feel comfortable putting a candidate in front of a client. To assess that, they ask themselves these questions:

• Is this person able to do the job? Do they have the analytic skills to solve tough business problems?
• Is this person client-ready? Are they knowledgeable, professional, and confident enough to work effectively with client staff and leaders?
• Is this someone I’d want to work with? This interview question is sometimes referred to as the airport test. It comes down to, “Would I want to be stuck in an airport with this person if the weather was bad and our flight was delayed?” It assesses whether an individual is smart, fun and passionate about the projects they take on.
• Is this person coachable? No one expects a recruit to know the answer to every thorny business issue right out of undergrad, or even right out of business school, but they do want someone who is willing and able to take suggestions and improve their analysis. Show you are coachable by listening for feedback as you answer a case study interview question and using suggestions to steer you toward the right solution.

Consulting Case Prep Takes Time – So Start Early

If you walk into your first consulting interview without having practiced case study interviews beforehand, you’re in for a painful experience. Case questions can cover any industry and multiple different types of business problems, so you’re unlikely to get lucky and know the answer.

We suggest your start your consulting case prep a few weeks before your interview. Starting with more lead time is even better. This will allow you to watch/read through a few consulting cases to get a sense for what to expect (continue to our case videos below for one example!) It will also give you time to find a couple friends or classmates who are also applying to consulting firms. You can give each other mock case interviews and be even more prepared.

Learn How to Case Quickly by Mastering Each of the 4 Parts of the Case

When you’re starting your consulting interview prep, it’s important to remember that the “right answer” is not simply a conclusion, but the methodical, the well-structured process used to reach the conclusion. 

To answer a case question correctly, you must:

Step 1: Understand the question you are being asked.

After your interviewer describes the client this case interview will involve and the problem they face, you should repeat this information back to them in your own words. 

This can feel awkward when you practice your first case, but it will help you in the long run.

If you don’t have the client and their problem straight, you could spend a lot of time answering the wrong question. If that happens you will not be moving forward to second round interviews no matter how elegant your analysis is.

Example: Our client is a fast-food retailer that has seen decreasing sales revenue over the past couple of years. They want your help in understanding what they can do to improve sales.

Step 2: Take time to think through all the key aspects of the problem.

Ask for a moment to consider your approach to solving the client’s problem. During this time, write down what you want to learn about the client’s situation before you answer the interview question.

Your approach can lean on business frameworks you’re familiar with during your case interview preparation. 

For instance, in the example of a fast-food chain with declining sales, you should break sales down into price and unit volume to understand whether the client is not selling enough units of their products or whether prices have fallen (or both!)

But you don’t need to use familiar frameworks. In fact, it’s best to develop your own structure for breaking down the problem as it shows you can solve a case without forcing a standard framework on the problem.

For more information on business frameworks, you might want to become familiar with during your case study preparation, see  Case Interview Frameworks .

Step 3: Ask pertinent questions and use information from the interviewer to form hypotheses about the problem and explore potential options.

After you brainstorm key aspects of the case problem and structure your approach to solving it, share your approach with your interviewer.

If the interviewer suggests a place to start your analysis, follow their lead.

Otherwise, suggest the best place to start digging into the case.

Make sure the questions you ask the interviewer touch on all the key aspects of the problem you identified including the client’s internal organization, the market for their product, and their competition.

Step 4: Summarize your case interview conclusion in a persuasive manner. 

Once you’re confident you have enough information to understand the case and what needs to be done to solve the client’s business problem, you’ll conclude the interview with a logical summary outlining the problem, key conclusions you’ve reached, and providing a persuasive recommendation on how you’d help the client resolve it.

Below, we’ll go into more depth on how to address each of these 4 points in a case.

Questions You Should Ask Yourself Before Diving Deeper into Case Interview Preparation

Right now, you may be thinking to yourself that consulting interviews sound impossibly difficult. Or you may think that they sound like interesting business problems that you’d enjoy solving. 

Perhaps you’re not sure.

If you think that answering case interviews is not something that would come naturally to you, don’t worry, you’re not alone! 

Getting good at consulting interviews requires a lot of preparation.

Before you commit to putting in the time required to prepare for the management consulting interview process, you should ask yourself if a career in management consulting is right for you.

Key Questions to Ask Yourself Before Pursuing a Career in Consulting

• Do you enjoy solving the types of business problems asked in case interviews?
• Do you have a background in business principles or are you willing to invest the time it will take to develop one?
• Are you passionate about pursuing consulting as a career?

Management consulting jobs might pay well and provide the opportunity to pursue attractive careers, but if you don’t like solving business problems, you probably won’t like the work you’ll do as a consultant. If you don’t enjoy analyzing business cases, save yourself a lot of preparation time and frustration. 

Focus on career options that better meet your interests.

Or, perhaps solving business problems with smart, driven professionals sounds like it’s your dream job. 

If so, move onto the deeper dive into case interview prep below! 

Case Interview Prep – Diving Deeper

If you’re here, we’re assuming you’re serious about investing time in preparing for a career in management consulting. 

The best way to get smarter about  answering case interview questions is to master this four-part approach.

How to Answer a Consulting Case Interview –  a 4 Part Approach to Practice During Interview Prep

The 4 parts to answering a consulting case interview are:

• Opening  – This is where you make sure you understand the client’s problem.
• Structure  – This is where you brainstorm all factors relevant to the problem and organize them to ensure you address them in a complete and logical manner.
• Analysis  – This is where you gather data to identify which of the factors related to the business case are the most important. You’ll use this data to create a recommendation for your client.
• Conclusion  – Here, you present your recommendation to “the client” (your interviewer), in a well-structured and persuasive manner.

Case Interview Prep Part 1: The Opening

As we saw in the video above, the opening of a case question is a description of a client and the problem they’re facing. Davis repeated back to the interviewer the type of business the client was in and and their business problem.

Remember, this clarification is an important step in the process.

If you did not remember that the client was a top-three beverage producer and answered the question as if the client was a start-up, your answer would ignore the manufacturing and distribution infrastructure the company already had in place to launch its new product.

That would make your answer completely wrong.

During this portion of the interview, you can ask any clarifying questions you need to. If something is not clear—the client’s product or industry, or the problem they want to solve —ask !

Nailing the opening is probably the easiest part of case interview preparation. Get this right, and you’ll start each case off strong.

Case Interview Prep Part 2: Structure

Once Davis clarified the problem, he asked for a moment to prepare her response. In the structure phase of the case interview, there’s silence for several moments.

As with clarifying the question, this can feel awkward.

But asking for this time will show the interviewer that you’re carefully structuring your problem-solving approach.

It will also ensure that you are not quickly addressing a couple of aspects of the business problem but ignoring others, potentially ones that are critical to solving the client’s problem.

Some quick brainstorming is useful here, but also take a step back to maker sure you consider all aspects of the client’s business, its customer demand, and the competition. 

Organize your questions into a comprehensive approach to address all key aspects of the problem.

Mastering the structure phase of the interview is not as easy as the opening, but it’s critical to ensure you have the structured problem-solving approach that will lead you to the right answer to the case.

Focus on this aspect of case interview preparation until you can structure almost every case right.

Case Interview Prep Part 3: Analysis

In the third part of the case study interview, you’ll dig in and analyze the problem.

After Davis outlined his problem-solving approach, the interviewer told him that the client wanted to understand the beverage market and customer preferences to assess the potential success of the product launch.

The interviewer then provided a chart with helpful data.

This part of the interview is important because gives you the data that will help you close down aspects of the case that aren’t at the heart of the problem you need to solve and to better understand key drivers that will point to the solution.

But you’ll also need to do some consulting math .

You should also refer back to the problem-solving structure you laid-out earlier in the interview to make sure your analysis is comprehensive. You don’t want to get lost down one rabbit hole and ignore other important aspects of the problem.

During this portion of the interview, you’ll be assessed on whether you asked relevant questions, have well-reasoned insights into the client problem, and whether you could lead a case like this if you were hired by the firm.

Many consulting candidates find that the analysis phase of the interview is the toughest of the 4 parts.

You need to balance doing consulting math calculations with interpreting data and make sure you cover all aspects of the problem you identified in the structure phase of the case. 

Stick with this aspect of case interview preparation until you’re an expert at it–it will pay off in your interviews. 

Case Interview Prep Part 4: Conclusion

Davis concluded the case with a direct answer to the case study interview question as it was initially asked.

This answer should be both persuasive and logical based on all the information gathered over the course of the interview. Your answer should also include the next steps your client should undertake.

During the conclusion, you’ll be assessed on whether you present a well thought-out solution based on the relevant facts of the case.

Like the opening, mastering the conclusion is not difficult. Take you time to nail this aspect of case interview preparation anyway as leaving your interviewer with a strong impression of your casing capabilities is important.

The Bottom Line for Effective Case Interview Prep

The case study interview is not as complex as it seems if you break it into 4 parts.

Practicing each part of the case on its own will make your consulting interview preparation both more efficient and more effective.

Now that you’re familiar with the 4-part approach to a case interview, the next thing to learn is the 4 different formats case interviews can take.

4 Formats for Case Interviews

There are four formats a consulting case interview can take:

• Candidate-led – This is the most typical case study interview format. A candidate is given an open-ended business problem to solve by an interviewer. The candidate will break down the question into key parts and decide which part to probe first. The interviewer is looking to see that you know how to drive the analysis of a problem. This case format is typically used at firms like Bain, BCG and Oliver Wyman.
• Interviewer-led – In this case interview format, a candidate will still be expected to identify and structure the key elements of  a thorny business issue, and then present them to the interviewer. But after they do, the interviewer will direct them to first address a particular aspect of the case. This interview format is typically used in McKinsey cases.
• Written interview – This is not a common interview format but can be common for particular companies and offices. You will be given a packet of PowerPoint slides and time to review them. During this time, you’ll prepare a presentation using the slides you choose from the ones provided as well as others you create, and you’ll then present it to a panel of interviewers. Written interviews are frequently used by boutique consulting firms and regional offices of larger firms such as Bain’s China offices. For more information, see this article on written case interview.
• Group interview – Multiple candidates are brought in to discuss a case together and then present their solution to an interviewer. The group case is also not a frequently used interview format. For more information, see this article on group case interview.

While the candidate-led consulting interview is the most frequently used format, you’ll probably see more of the interview-led interview format in McKinsey interviews.

You should also be aware of the written and group interview formats so that if you get one during the interview process, you’re not caught by surprise. But don’t spend a lot of time on preparation for that type of interview unless you’re informed you’ll have one.

Congratulations! 

You’ve made it to the end of our crash course on case interview prep. By reading this article, you now have a strong understanding of:

• What a consulting case interview is,
• How to answer case studies using the 4-part approach, and
• What the 4 different formats for case interviews are.

You are well on your way toward preparing for your first case interview and entering the exciting field of management consulting.

8 thoughts on “A Comprehensive Guide to Case Interview Prep [updated 2024]”

In the math calculations of the analysis portion, why was it that there were 8 cans per gallon? Where did that number come from?

Hey, Tonia! Thanks for your question.

In the case, we’re given that the size of the market for US sports drinks is 8 billion gallons. Electrolyte drinks are 5% of this total or .4 billion gallons which equals 400 million gallons.

We’re also given that the product size for drinks in this market are 16 ounces. And in our breakeven analysis, we find out we need to sell 400 million bottles (or cans) to break even. We need to do a conversion to compare our breakeven point of 400 million bottles to the 400 million gallon market size to see what market share we would have to achieve to break even.

Conversion: 1 US gallon = 128 ounces. 128 ounces/ gallon divided by 16 ounces/ bottle = 8. We can fill 8 bottles for each gallon of electrolyte drink we produce. So 1 gallon is 8 bottles (or cans) manufactured by our client.

We divide the 400 million bottle (or can) breakeven point by 8 to get to 50 million gallons. We compare the 50 million gallon breakeven point to the 400 million gallon market size to see that we need to capture 12.5% market share.

Note: In answering this question, I noticed that a UK gallon = 160 ounces, so if you are using UK gallons you will get a different answer!

I hope that helps! Sorry about the confusion between US ounces/gallon and UK ounces/gallon!

Hi, what resources are you typically allowed to use during (virtual) case interviews? Such as a pen, paper, calculator etc.

You’re typically allowed a pen and paper in a virtual case interview but NOT a calculator. Part of what your interviewer is testing for is your quantitative skills, so they want to see that you can do calculations in your head or on paper. See our article on virtual case interviews , for more info. Also, we have an article on practicing your case interview math .

Best of luck!

Can you please explain the ROI formula? I do not understand why (2m-8m)/8m = 25%. That calculation gets a result of -75%

Shouldn’t the formula just be (net profit)/(cost of investment)?

George, thanks for pointing this out! The formula was incorrect, and should be Profit/cost of investment. The correct answer is 25%.

All the best, MCO

thanks for information

great information

A Guide for Case Study Interview Presentations

You’ve been called for an interview at your dream firm and spent the entire night rote learning policies, laws, and theories to impress the panel of interviewers with your ability to retain knowledge. However, when the interview presentation begins, contrary to your expectations of being asked to recall the information you’ve memorized, you are handed a piece of paper, which entails details about a financial embezzlement scandal. You are instructed to analyze the document and provide solutions to the problems mentioned at the end of the document.

The above-mentioned hypothetical situation is an example of a case study interview, often used by professional services firms to assess and hire applicants.

Table of Contents

What is a case study interview?

Why a case study interview, format of a case study interview, non-profitability cases, startup and early stage ventures, market sizing framework, profitability framework, market study framework, merger & acquisition cases framework.

• Example Scenario 1

Example Scenario 2

A case study interview is one in which the candidate is interviewed about a scenario-based business organizational challenge that the company may have experienced. The case interview allows candidates interested in a career in consulting to exhibit their analytical, communication, and reasoning abilities. The case study interviews are constructed in such a way that they aid in identifying key issues in order to develop effective solutions. ( LSE )

To gauge a potential employee’s ability to apply theoretical knowledge to real-world situations and develop workable answers in a constrained amount of time, interviewers use the case study interview method. Big market players, like McKinsey, Deloitte, or Bain and company, use case studies in their job interviews . The interviewer may measure a candidate’s ability not just to grasp technical elements of a real-life problem, but also to come up with creative solutions, by asking case study questions.

Case study interviews are often carried out in one of two ways, depending on the goals and specifications of the company conducting the interview.

• Interviewer-led interview
• Candidate led Interview

Interviewer led

During a case study interview, the interviewer is the one who sets the tone, pace, and overall structure. It is a highly structured interview where the candidate should be prepared for a sudden change of style depending on the interviewer. The interviewer continues asking questions they’ve already prepared regardless of the candidate’s answers.

Candidate led

In contrast to an interviewer-led, a candidate-led is less regimented, and the candidate takes the wheel. They are expected to shape the Interview from start to finish. In this case, the candidate’s answers determine the line of questions. It is convenient for a firm to assess if an individual can handle situations independently by conducting a candidate-led interview.

In the final section, we’ve provided candidate- and interviewer-led interview cases in our examples.

Archetypes of Case Study Interviews

Not every case study interview is centered on profit or revenue-generating scenarios. The interviewer may begin with a case of Non-Profitability. The analyzed organization might face a challenge to reach an objective. It requires a situation analysis in order to provide a diagnosis. The candidate will run the analysis, provide a diagnosis, and based on it will define a strategy to overcome the challenge and reach the objective. 

During the case interview, the focus is on strategic issues and recommendations for developing an industry’s environment while dealing with challenges. Regulations, consumer preferences, and more might all fall under this umbrella. Here, a SWOT analysis is useful in identifying the competitive landscape.

Taking into account the emerging Industrial Revolution 4.0 startup boom. The interviewer will most likely use this as an example in your case study interview. Market entry cases are comparable to startup, and early venture case studies, except the company, is smaller and employs fewer people. One must have a strong product or service in order to have a foothold in the market with significant profit margins.

The case study discussion should focus on the following three areas: the right people, the right problem, and the right solution. A minimum viable product and a well-thought-out business strategy are necessary. Startups are more likely to be agile and successful when these three characteristics are present.

In a market sizing question, commonly known as ‘guesstimate,’ the candidate is asked to estimate the size of a market randomly selected by the interviewer with little or no data available. Market size questions should be approached by segmenting data and adapting the MECE technique. In a case study interview, you may also solve market sizing problems by using the issue decision tree .

 Case study interview questions can be the following:

• Estimate the market size of frozen foods in a suburban area of Melbourne.
• How many individuals are currently consuming vitamin water in China?

Every firm’s ultimate goal is to earn profits; therefore, the profitability framework seeks to identify whether the candidate can correctly assess the cause of decreased profitability or ways of increasing profitability. Candidates are usually provided with names, figures, and facts to answer questions pertaining to different aspects of profitability.

A market study framework generally aids in determining an individual’s ability to assess market factors like market entry potential, revenue growth, and market share.

In order to construct a framework for a market study in a case interview, the candidate must focus on five components. The market, rivals, customers, your firm, and your product/service are all included. This market analysis methodology necessitates the candidate to ask further clarifying questions on the financial and profitability impact on the company in discussion.

The merger and acquisition cases framework is considered one of the most accurate judges of the candidate’s potential as it deals with all major components of market analysis, including but not limited to market sizing, profitability, and market study factors. These case study interview questions usually deal with whether or not two or more companies should opt for a merger/acquisition.

When addressing an M&A case, three components should be taken into account: the synergies between the two organizations, the integration of talent, technology, and so on, and regulatory approvals.

Case Study Interview Example Scenario 1

Objective: Country X is situated in Asia and has a population of 20 million. It is developing a national action plan to transform its education system. It wants to improve the quality and quantity of children’s education. The objective is to advise the client on transforming their education system.

Description: Country X is a developing nation of 20 million residents and has emerged as a free market economy after spending decades under communism. The Country aspires to have an economic action plan for transforming education. The schooling system in Country X is completely public (state managed) and has government-run schools spread throughout the Country. Children are admitted from age 5 to 18. The objective is to evaluate the current state of the education system and how it can meet the aspirations of the Government. 

This type of scenario mostly follows an interviewer-led approach. This falls under the Non-Profitability case study example. The primary purpose is to examine the issue from the top-down approach to get a higher-level view. Initially, qualitative analysis is performed.

• The interviewer will first ask how you intend to analyze and evaluate the problem’s underlying issues.

An approach is to structure the response into three sections. A PowerPoint slide with a clear bifurcation of these three sections can be presented under a separate heading.

The initial section should emphasize some quantitative metrics of education. This encompasses observations such as how age, gender, and geography affect access to education. How many teachers are working in schools around the region? How much is spent on healthcare?

The second component is the quality of education, including the curriculum, teaching methods, etc. The second question is quantitative and requires analysis of a table containing distinct informational values relative to competitor nations.

A third element of the analysis could be to understand the effect of education in Country X’s economics objectives.

You will be provided with a table with figures for the number of pupils and teachers, health care expenditure, student-to-teacher ratio, etc. You will be expected to evaluate competitor values in comparison to Country X. Among the observations that can be made are how Country X compared to other nations regarding health care spending and the student-to-teacher ratio. The table values can be interpreted as, e.g., Country X has the highest education expenditure but has the lowest student-to-pupil ratios. All this information can be presented using SlideModel PowerPoint templates .

Comparing the observation to international standards is another way of acquiring a deeper understanding of the provided data. Because only 15 percent of Country X’s population is enrolled in school, the question is how many schools should be opened given that Country Y surpasses Country X in an international comparison. To solve such a puzzle, you will use comparable data to compute the number of schools utilizing population and school information from the provided data. This will assist you in determining a solid number to present in the Interview. The final number can be presented as a percentage or an absolute number in a much larger font on the ppt slide. SlideModel has a variety of case study templates you can choose from to showcase your result in a much more engaging manner.

These two approaches for the qualitative and quantitative aspects of the case Interview enable us to cover the fundamentals of a case study interview. 

Objective: Client Y is about to launch a new phone and desires to determine the size of the Apple product market. The objective is to determine how many iPhones Apple sells in the United States annually.

Description: Client X seeks an analysis of the current market size of the iPhone, its primary rival in the mobile phone industry. The current population of the United States is 320 million, and iPhone has a very large client base in the Country. The client requests that you calculate a number that provides a reliable estimate of the size of the iPhone market in the United States.

We will use a Three-step technique for a market size example to tackle this problem.

Step 1: Formulate the right question

To define market size, asking appropriate clarifying questions is a must. It is useful to define what the market size is and how to give a proper estimate for the market segment based on the given information.

For example:

Are we concentrating on a single iPhone model or the entire lineup?

Is it simply applicable to the United States, or do we also need to estimate worldwide iPhone sales through the US outlet?

After asking the appropriate clarifying questions, you can formulate a coherent strategy.

Step 2: Building a Framework

There are two sorts of problem-solving strategies for gauging the market questions. The top-down method and the bottom-up method.

The appropriate and easy way to solve this is to utilize top-down methodology and show it via an Issue tree. Using the MECE (Mutually conclusive and Collectively exhaustive) technique , an issue tree is a logical tree that may be depicted graphically to address difficult business challenges. It is quite common in market size questions. On the SlideModel website, you will discover a choice of templates for creating an excellent visual tool, i.e., The Issue/Logic tree.

You might convey it by beginning with the United States 320 million people.

Determine what proportion of phones are iPhones.

Identifying the frequency with which an individual purchases an iPhone each year.

And determine the number of iPhones sold based on the frequency and quantity of iPhone owners.

Step 3: Estimating and making assumptions

The estimated population of the United States is 320 million. Assuming that 75 percent of the United States population possesses a mobile phone and 30% are iPhone users because the number of smartphone users has multiplied in the digital era, we obtain: 

75 % x 320 million = 240 million Mobile Phone users.

30 % x 240 million = 72 million iPhone users.

Again, we suppose that each of these 72 million people buys an iPhone every two years. A single client will acquire one iPhone 0.5 times in a year.

Therefore, 0.5 times 72 million is 36 million iPhone sales.

To estimate the size of the iPhone market in the United States, we might assume the average iPhone price is $100.

By calculating the cost by the number of units sold a year, we get:

$100 x 36,000,000 = $3.6 billion USD.

Therefore, the annual market size for apple goods is $3.6 billion.

Calculations and estimations utilizing the said frameworks require practice and findings. SlideModel will assist you in organizing your framework and offer you visual tools to successfully convey your findings to the interviewer.

How to Present a Case Study like a Pro (With Examples)

By Danesh Ramuthi , Sep 07, 2023

Okay, let’s get real: case studies can be kinda snooze-worthy. But guess what? They don’t have to be!

In this article, I will cover every element that transforms a mere report into a compelling case study, from selecting the right metrics to using persuasive narrative techniques.

And if you’re feeling a little lost, don’t worry! There are cool tools like Venngage’s Case Study Creator to help you whip up something awesome, even if you’re short on time. Plus, the pre-designed case study templates are like instant polish because let’s be honest, everyone loves a shortcut.

What is a case study presentation?

What is the purpose of presenting a case study, how to structure a case study presentation, how long should a case study presentation be, 5 case study presentation examples with templates, 6 tips for delivering an effective case study presentation, 5 common mistakes to avoid in a case study presentation, how to present a case study faqs.

A case study presentation involves a comprehensive examination of a specific subject, which could range from an individual, group, location, event, organization or phenomenon.

They’re like puzzles you get to solve with the audience, all while making you think outside the box.

Unlike a basic report or whitepaper, the purpose of a case study presentation is to stimulate critical thinking among the viewers. 

The primary objective of a case study is to provide an extensive and profound comprehension of the chosen topic. You don’t just throw numbers at your audience. You use examples and real-life cases to make you think and see things from different angles.

The primary purpose of presenting a case study is to offer a comprehensive, evidence-based argument that informs, persuades and engages your audience.

Here’s the juicy part: presenting that case study can be your secret weapon. Whether you’re pitching a groundbreaking idea to a room full of suits or trying to impress your professor with your A-game, a well-crafted case study can be the magic dust that sprinkles brilliance over your words.

Think of it like digging into a puzzle you can’t quite crack . A case study lets you explore every piece, turn it over and see how it fits together. This close-up look helps you understand the whole picture, not just a blurry snapshot.

It’s also your chance to showcase how you analyze things, step by step, until you reach a conclusion. It’s all about being open and honest about how you got there.

Besides, presenting a case study gives you an opportunity to connect data and real-world scenarios in a compelling narrative. It helps to make your argument more relatable and accessible, increasing its impact on your audience.

One of the contexts where case studies can be very helpful is during the job interview. In some job interviews, you as candidates may be asked to present a case study as part of the selection process.

Having a case study presentation prepared allows the candidate to demonstrate their ability to understand complex issues, formulate strategies and communicate their ideas effectively.

The way you present a case study can make all the difference in how it’s received. A well-structured presentation not only holds the attention of your audience but also ensures that your key points are communicated clearly and effectively.

In this section, let’s go through the key steps that’ll help you structure your case study presentation for maximum impact.

Let’s get into it. 

Open with an introductory overview 

Start by introducing the subject of your case study and its relevance. Explain why this case study is important and who would benefit from the insights gained. This is your opportunity to grab your audience’s attention.

Explain the problem in question

Dive into the problem or challenge that the case study focuses on. Provide enough background information for the audience to understand the issue. If possible, quantify the problem using data or metrics to show the magnitude or severity.

Detail the solutions to solve the problem

After outlining the problem, describe the steps taken to find a solution. This could include the methodology, any experiments or tests performed and the options that were considered. Make sure to elaborate on why the final solution was chosen over the others.

Key stakeholders Involved

Talk about the individuals, groups or organizations that were directly impacted by or involved in the problem and its solution. 

Stakeholders may experience a range of outcomes—some may benefit, while others could face setbacks.

For example, in a business transformation case study, employees could face job relocations or changes in work culture, while shareholders might be looking at potential gains or losses.

Discuss the key results & outcomes

Discuss the results of implementing the solution. Use data and metrics to back up your statements. Did the solution meet its objectives? What impact did it have on the stakeholders? Be honest about any setbacks or areas for improvement as well.

Include visuals to support your analysis

Visual aids can be incredibly effective in helping your audience grasp complex issues. Utilize charts, graphs, images or video clips to supplement your points. Make sure to explain each visual and how it contributes to your overall argument.

Pie charts illustrate the proportion of different components within a whole, useful for visualizing market share, budget allocation or user demographics.

This is particularly useful especially if you’re displaying survey results in your case study presentation.

Stacked charts on the other hand are perfect for visualizing composition and trends. This is great for analyzing things like customer demographics, product breakdowns or budget allocation in your case study.

Consider this example of a stacked bar chart template. It provides a straightforward summary of the top-selling cake flavors across various locations, offering a quick and comprehensive view of the data.

Not the chart you’re looking for? Browse Venngage’s gallery of chart templates to find the perfect one that’ll captivate your audience and level up your data storytelling.

Recommendations and next steps

Wrap up by providing recommendations based on the case study findings. Outline the next steps that stakeholders should take to either expand on the success of the project or address any remaining challenges.

Acknowledgments and references

Thank the people who contributed to the case study and helped in the problem-solving process. Cite any external resources, reports or data sets that contributed to your analysis.

Feedback & Q&A session

Open the floor for questions and feedback from your audience. This allows for further discussion and can provide additional insights that may not have been considered previously.

Closing remarks

Conclude the presentation by summarizing the key points and emphasizing the takeaways. Thank your audience for their time and participation and express your willingness to engage in further discussions or collaborations on the subject.

Well, the length of a case study presentation can vary depending on the complexity of the topic and the needs of your audience. However, a typical business or academic presentation often lasts between 15 to 30 minutes. 

This time frame usually allows for a thorough explanation of the case while maintaining audience engagement. However, always consider leaving a few minutes at the end for a Q&A session to address any questions or clarify points made during the presentation.

When it comes to presenting a compelling case study, having a well-structured template can be a game-changer. 

It helps you organize your thoughts, data and findings in a coherent and visually pleasing manner. 

Not all case studies are created equal and different scenarios require distinct approaches for maximum impact. 

To save you time and effort, I have curated a list of 5 versatile case study presentation templates, each designed for specific needs and audiences. 

Here are some best case study presentation examples that showcase effective strategies for engaging your audience and conveying complex information clearly.

So, you’ve spent hours crafting the perfect case study and are now tasked with presenting it. Crafting the case study is only half the battle; delivering it effectively is equally important.

Forget boring reports and snooze-inducing presentations! Let’s make your case study sing. Here are some key pointers to turn information into an engaging and persuasive performance:

• Know your audience : Tailor your presentation to the knowledge level and interests of your audience. Remember to use language and examples that resonate with them.
• Rehearse : Rehearsing your case study presentation is the key to a smooth delivery and for ensuring that you stay within the allotted time. Practice helps you fine-tune your pacing, hone your speaking skills with good word pronunciations and become comfortable with the material, leading to a more confident, conversational and effective presentation.
• Start strong : Open with a compelling introduction that grabs your audience’s attention. You might want to use an interesting statistic, a provocative question or a brief story that sets the stage for your case study.
• Be clear and concise : Avoid jargon and overly complex sentences. Get to the point quickly and stay focused on your objectives.
• Use visual aids : Incorporate slides with graphics, charts or videos to supplement your verbal presentation. Make sure they are easy to read and understand.
• Tell a story : Use storytelling techniques to make the case study more engaging. A well-told narrative can help you make complex data more relatable and easier to digest.

Nailed your case study, but want to make your presentation even stronger? Avoid these common mistakes to ensure your audience gets the most out of it:

Overloading with information

A case study is not an encyclopedia. Overloading your presentation with excessive data, text or jargon can make it cumbersome and difficult for the audience to digest the key points. Stick to what’s essential and impactful. Need help making your data clear and impactful? Our data presentation templates can help! Find clear and engaging visuals to showcase your findings.

Lack of structure

Jumping haphazardly between points or topics can confuse your audience. A well-structured presentation, with a logical flow from introduction to conclusion, is crucial for effective communication.

Ignoring the audience

Different audiences have different needs and levels of understanding. Failing to adapt your presentation to your audience can result in a disconnect and a less impactful presentation.

Poor visual elements

While content is king, poor design or lack of visual elements can make your case study dull or hard to follow. Make sure you use high-quality images, graphs and other visual aids to support your narrative.

Not focusing on results

A case study aims to showcase a problem and its solution, but what most people care about are the results. Failing to highlight or adequately explain the outcomes can make your presentation fall flat.

How to start a case study presentation?

Starting a case study presentation effectively involves a few key steps:

• Grab attention : Open with a hook—an intriguing statistic, a provocative question or a compelling visual—to engage your audience from the get-go.
• Set the stage : Briefly introduce the subject, context and relevance of the case study to give your audience an idea of what to expect.
• Outline objectives : Clearly state what the case study aims to achieve. Are you solving a problem, proving a point or showcasing a success?
• Agenda : Give a quick outline of the key sections or topics you’ll cover to help the audience follow along.
• Set expectations : Let your audience know what you want them to take away from the presentation, whether it’s knowledge, inspiration or a call to action.

How to present a case study on PowerPoint and on Google Slides?

Presenting a case study on PowerPoint and Google Slides involves a structured approach for clarity and impact using presentation slides :

• Title slide : Start with a title slide that includes the name of the case study, your name and any relevant institutional affiliations.
• Introduction : Follow with a slide that outlines the problem or situation your case study addresses. Include a hook to engage the audience.
• Objectives : Clearly state the goals of the case study in a dedicated slide.
• Findings : Use charts, graphs and bullet points to present your findings succinctly.
• Analysis : Discuss what the findings mean, drawing on supporting data or secondary research as necessary.
• Conclusion : Summarize key takeaways and results.
• Q&A : End with a slide inviting questions from the audience.

What’s the role of analysis in a case study presentation?

The role of analysis in a case study presentation is to interpret the data and findings, providing context and meaning to them. 

It helps your audience understand the implications of the case study, connects the dots between the problem and the solution and may offer recommendations for future action.

Is it important to include real data and results in the presentation?

Yes, including real data and results in a case study presentation is crucial to show experience,  credibility and impact. Authentic data lends weight to your findings and conclusions, enabling the audience to trust your analysis and take your recommendations more seriously

How do I conclude a case study presentation effectively?

To conclude a case study presentation effectively, summarize the key findings, insights and recommendations in a clear and concise manner. 

End with a strong call-to-action or a thought-provoking question to leave a lasting impression on your audience.

What’s the best way to showcase data in a case study presentation ?

The best way to showcase data in a case study presentation is through visual aids like charts, graphs and infographics which make complex information easily digestible, engaging and creative. 

Don’t just report results, visualize them! This template for example lets you transform your social media case study into a captivating infographic that sparks conversation.

Choose the type of visual that best represents the data you’re showing; for example, use bar charts for comparisons or pie charts for parts of a whole. 

Ensure that the visuals are high-quality and clearly labeled, so the audience can quickly grasp the key points. 

Keep the design consistent and simple, avoiding clutter or overly complex visuals that could distract from the message.

Choose a template that perfectly suits your case study where you can utilize different visual aids for maximum impact.

Primary school offer day 2024: Everything you need to know

Parents of three and four-year-olds will soon find out what primary school has offered their child a place for the next academic year.  

The majority of pupils will be offered a place at one of their preferred primary schools, while most will be offered their top choice.   

Here, we explain everything you need to know about primary school offer day, from when you can expect to find out, to how to appeal a decision.  

When is primary school offer day and what time are school places released?   

Parents will find out which primary school has offered their child a place for September 2024 on  Tuesday 16 April.

The decision will be sent by the local council by either letter or email. Some councils allow parents to view their results through the admissions portal or system. Exactly what time the offers will be released varies by council.

How likely am I to get my first-choice primary school?  

We want parents to feel reassured when it comes to getting one of their top choice primary schools.

In 2023, 92.5% of families received an offer from their first choice of primary school and 98.3% received an offer from one of their top three choices.

At the same time, over 1 million additional school places have been created between May 2010 and May 2023, with many more in the pipeline.

What happens after I receive an offer of a school place?  

A parent or carer must formally accept the offer by the given deadline. This is usually set through the local authority’s admissions portal or system. You’ll receive details of next steps with the offer.  

Can I appeal a primary school placement decision?  

If you’re not offered your first-choice school, you can appeal the decision . However, even if you're appealing a decision, we recommend accepting the offer your child did receive so that they have a school place if the appeal is unsuccessful. Accepting another offer won’t affect your appeal or limit other options available to you.  

Parents or carers who want to appeal a decision should first contact the school’s admission authority, which is responsible for organising the appeal panel. Parents and carers can find their school’s admission authority by visiting their local council website:  Find your local council - GOV.UK (www.gov.uk) .  

The panel is independent and will look at the case presented by both the admission authority and the parent before coming to a decision.  

The decision of the appeal panel is binding – if the appeal is upheld, the admission authority must offer your child a place at the school.  

Admission authorities and appeal panels must comply with the statutory School Admission Appeals Code, which is available  here . Guidance for parents on the admission appeals process can also be found  here .  

How are primary school places decided?  

All schools have admission criteria to decide which children get places. This criteria is set by the school or local council.  

While all state-funded schools must give top priority to admitting children who are in care or have been in care, admission criteria is  different for each school. They may choose to give priority to children:  

• who live close to the school  
• who have a brother or sister at the school already  
• from a particular religion (for faith schools)  
• who are eligible for the pupil premium   
• whose parent has worked at the school for two years or more  

Your  local council  can give you information about a school’s criteria.  

Why has my child not been offered a place at one of their preferred schools?  

Some schools will receive more applications than places it has available and unfortunately not every parent will be successful. Priority must be given to those who most closely meet the school’s specific admission arrangements.  

If the local authority is unable to offer a place at one of the parents’ preferred schools, it must offer a place at another school.  

In the unlikely event that a parent does not receive an offer of a place on 17 April, parents should contact their local authority for further advice.  

Can I join a waiting list for my top-choice primary school?  

You can add your child’s name to the waiting list for any school that you’ve applied for. You should still accept the offer you received and this won’t affect where you stand in the waiting list.  

Schools must keep a waiting list for at least one term. The waiting list will be ordered by the school’s oversubscription criteria.   

In some areas, your child will be automatically added to the waiting lists of the schools you ranked more highly. In others, you must ask to be put on the waiting list. Check the school admissions section of your local authority website to find out how it works in your area.

PITCH: Legal Analysis of Hush Money Trial facing former President Donald Trump

Legal Analysis of the Trump Hush Money Case

By Gregory Germain , Professor of Law

To request an interview with Professor Germain, please contact Ellen James Mbuqe, executive director of media relations, at [email protected].

Donald Trump’s criminal trial in New York begins today with jury selection.  The following is a summary and legal analysis of this very complicated case.

District Attorney Alvin Bragg alleges that, shortly before the 2016 presidential election between Donald Trump and Hilary Clinton, Trump made several arrangements to prevent the public disclosure of allegations against him that might negatively affect his election.

First, Trump arranged with American Media, Inc., the publisher of the National Enquirer, to “catch and kill” stories that might be embarrassing to Trump.  The National Enquirer paid for and killed two potential stories:  one from a doorman who alleged that Trump had fathered a child out of wedlock, which proved to be untrue, and a second from a former Playboy model Karen McDougal, who claimed to have had an affair with Trump during his marriage.

Second, and more importantly, for the actual charges in the indictment, Trump arranged with his then-lawyer and now chief nemesis, Michael Cohen, to pay $130,000 in “hush money” to Stephanie Clifford, known professionally as Stormy Daniels, who is described by Wikipedia as “an American pornographic film actress, director and former stripper,” to prevent her from disclosing a sexual relationship with Trump.

Trump disguised the hush money payments by having Cohen make the payments, and then reimbursing him using business entries that called the payments “attorney fees”.

Trump has never been charged with a crime for making the hush money payments or arranging with AMI to catch and kill stories.  The underlying charges were investigated by the US Attorney General’s office, and they decided not to bring criminal charges against Trump.

There has been some suggestion that the hush money payments might somehow violate federal election laws, although I have never understood how using one’s own money to pay for the non-disclosure of embarrassing allegations would violate the election laws, which are primarily concerned with the solicitation and use of campaign contributions by third parties.  Even if the government wanted to charge Trump now for violating the election law in 2016, those charges would likely be barred by the applicable statute of limitations.

The underlying case is somewhat like the criminal charges brought against former presidential candidate John Edwards, who was charged in 2011 with receiving more than $900,000 in illegal campaign contributions from friends in 2007-08 to make hush money payments to disguise his extramarital relationship and child from becoming public.  The Edwards case involved money from third parties, so the election law connection makes some sense.  Nevertheless, the jury found Edwards not guilty of violating the campaign finance laws, and the government decided not to further pursue the remaining charges that the jury was unable to decide.  Ironically, Jack Smith, the current special prosecutor in the federal classified documents and election interference cases, had directed the Edwards prosecution.

Instead of charging Trump with an underlying crime, District Attorney Bragg is charging Trump only with covering up an underlying crime.

NY penal law 175.05 makes it a “class A misdemeanor” to falsify business records with “intent to defraud.” Falsifying business records to commit a fraud becomes a Class E felony “when his intent to defraud includes an intent to commit another crime or to aid or conceal the commission thereof.”  NY Penal Law § 175.10.

District Attorney Bragg’s indictment charges Trump with 34 felony counts, each of which relates to a business record disguising a payment made to Cohen as attorney fees.  The indictment alleges that Trump disguised the payments with intent to cover up another crime.  But the indictment does not say what that other crime is.

There are several layers that I believe District Attorney Bragg must show to convict Trump of committing a felony under Penal Law § 175.10.

First, Bragg must show that Trump made the false business records with intent to commit “fraud,” otherwise Trump would not be guilty of a crime at all, because falsifying business records for non-fraudulent purposes is not a crime under the statute.

It is not clear who Bragg believes Trump intended to defraud by falsifying these entries.  Presumably, Trump was trying to hide the allegations and/or the relationships from his family and/or the public to prevent the disclosure of embarrassing allegations or facts, but traditional “fraud” requires, among other things, showing an intent to receive financial benefits by misleading a victim, and the misrepresentations must cause an actual victim to suffer damages.  Fortunately for politicians, not all lies, misrepresentations, or nondisclosures constitute “fraud.”

The District Attorney has made public statements suggesting that Trump may have been hiding the payments as attorney fees to commit tax fraud, but neither that nor any other specifics regarding an intent to commit fraud is stated in the indictment.

Second, the District Attorney must show that the reason for Trump’s false entries was to commit or cover up a separate crime , presumably separate from the fraud.  If the separate crime is the election law violation, Trump would have had to know that the payment was an election law violation, and to have falsified the records to cover it up that crime.  It seems to me that the election law violation would be stronger, not weaker, by making it look like Cohen was the one making the payments for Trump.  Disguising the payments through Cohen made it look more like an election law violation by a supporter, not less.   Or was Trump trying to disguise the payments to prevent his family or the public from knowing about the embarrassing allegations, rather than covering up an independent crime?

I believe the District Attorney must show (1) that the payments were disguised as attorney fees to commit a fraud on someone, (2) that the underlying payments constituted an independent crime, (3) that Trump knew that the underlying payments constituted a crime, and (4) that the reason he covered up the payments was to disguise that crime.  Those are going to be hard things to prove.

Judge Merchan’s summary of the case for the jury glosses over all of these difficult statutory questions.  After being unable to get the parties to agree on the language of a statement to be read to the jurors to describe what the case is about, Judge Merchan decided to read the following statement to the jurors to summarize the case:

“The allegations reflect in substance, that Donald Trump falsified business records to conceal an agreement with others to unlawfully influence the 2016 presidential election . Specifically, it is alleged that Donald Trump made or caused false business records to hide the true nature of payments made to Michael Cohen, by characterizing them as payment for legal services rendered pursuant to a retainer agreement. The People allege that in fact, the payments were intended to reimburse Michael Cohen for money he paid to Stephanie Clifford, also known as Stormy Daniels, in the weeks before the presidential election to prevent her from publicly revealing details about a past sexual encounter with Donald Trump.”

Judge Juan Merchan’s statement fails to explain when it is a crime to “unlawfully influence” an election?  Obviously, all politicians attempt to influence voters to vote for them.  Politicians regularly misstate facts and fail to disclose facts during their campaign.  The law has never allowed members of the public or the government to bring claims for fraud against politicians who make misleading or even downright false statements; indeed our laws broadly protect campaign speech under the First Amendment.

Neither the Court nor the District Attorney has made it clear who was defrauded, what the independent crime is, or when an attempt to influence voters becomes “unlawful” and constitutes an independent crime.

There is also a question regarding the statute of limitations applicable to these claims.  The statute of limitations on a misdemeanor in New York is 2 years, and would have expired long ago.  NY Crim Proc 30.10(2)(c).  The statute of limitations on “other felonies” is 5 years.  NY Crim Proc. § 30.10(2)(b).  The acts occurred in 2016 and 2017, and the District Attorney delayed filing the charges for several years.  The District Attorney has argued that the statutes of limitations were tolled during COVID, or that they were extended when Trump left the state.  These issues need to be addressed by the court clearly.

So while there is very strong evidence that Trump created false business record entries to cover up his hush money payments to Stormy Daniels, the District Attorney needs to show multiple difficult elements to establish that the entries were made to commit “fraud,” and for the purpose of covering up a separate crime.

Finally, what is the penalty if Trump is convicted of this Class E felony? He would be subject to a fine of up to $5,000 under NY Pen § 80.1.  If he received some financial benefit, he might have to disgorge three times the amount of the benefit.  It is difficult to see how these minor penalties would justify such an expensive investigation and prosecution.

So the goal must be to impose imprisonment.  For a first time offender, the court could impose a prison term of up to one year under NY Penal law § 70(4), but it would be very unusual to impose prison time for a first time Class E felony, especially where no victim suffered financial harm.

This case is an important test for our legal system.  District Attorney Alvin Bragg was under intense political pressure to bring these charges, even after his predecessor, Cyrus Vance Jr., decided not to do so.  Trump is very unpopular in Manhattan, and has acted boorishly and foolishly in verbally attacking parties, judges, court clerks and their families.  But the law must be applied fairly and evenly to all parties, even those who are locally unpopular, and it is the District Attorney’s responsibility to assure equal treatment under the law.

I believe that the use of our legal system for political purposes will backfire with the electorate.  Every time a politically motivated case is decided, the polls show Trump becoming more popular.  Alvin Bragg sits in the chair once occupied by one of my legal heroes, Robert Morgenthau, who refused to use his office for political purposes, and had the courage to admit when his office made mistakes.  Bragg has a lot to live up to.  This old case, with all of its legal difficulties, should not have been brought

How smart storage lockers support flexibility for hybrid workers

Smart locker systems make flexible workspaces in offices appealing to employees and optimize space for employers.

How EY can help

The better the question

Is the employee experience you’re delivering the one your people want?

Different and smarter personal storage solutions are critical to advancing the employee experience.

The global EY organization has become a leader in agile work environments by recognizing that flexibility is no longer a culture-driven perk — flexibility is essential to employee retention now and going forward. To deliver the employee experience our people want, we reimagined the workplace configuration and design of our headquarters at One Manhattan West in New York to create a workplace that meets the demands of the hybrid worker. We focused on how workers will use the office space and how we could meet and surpass their expectations.

“When employees visit the office, they do so for a purpose. It could be seeing friends, a social event, or a meeting with team members, a client or a supervisor,” said David Kamen, EY Americas Real Estate Services Leader. “Instead of a sea of cubicles, there is more variety of spaces, rooms and collaborative places that all support a more adaptable approach to how work gets done.”

To make these new collaborative spaces function for the most people possible, One Manhattan West does not have designated desks for employees. This change supports flexibility, but we knew our people would need in-office storage that functions with and complements these flexible workspaces.

Our smarter workspaces necessitated incorporating smarter storage. Previously, employees struggled to get a locker close to where they would be working for the day. Lockers were typically assigned and would always be in one spot, regardless of work location. Smart lockers solve this problem, enabling employees to reserve a locker wherever their workspace is for that day.

The better the answer

Smart storage within an integrated technology ecosystem

Smart lockers help EY people manage, control and optimize storage on a self-service basis.

Employee expectations of smart technology have become critical in building infrastructure and improving the workplace experience. The growth of the Internet of Things (IoT) has sparked a further push to allow systems to talk to each other through common protocols and open standards, creating a digital ecosystem.

Smart locker systems are now part of the EY digital ecosystem. They are a combination of hardware and software, with a software-as-a-service (SaaS) platform at the heart, where the locker management takes place. Any physical locker cabinet can become a managed smart locker through the integration of smart locker system hardware and software.

The hardware, usually in the form of an electronic lock, is connected to an operating terminal, which is then connected through the internet to a SaaS platform. This software platform is the most critical component of a successful smart locker system, as this is where an organization defines the criteria under which lockers can be used and integrates with all other IoT and IT systems.

In the previous EY office, it was a challenge for employees to get a locker near their desk. Assigned lockers, and people’s assigned desks, were in one spot. Now, the new office’s design encourages activity-based working, which means using different work settings in the office based on the task at hand. Employees can use an individual workstation for day-to-day work, a collaboration room for smaller groups or a meeting room for larger groups. As part of the EY digital ecosystem, smart locker systems empower employees to choose where they want to work and find and use convenient storage throughout the day.

One Manhattan West employees can use their EY access badge at an integrated walk-up kiosk to book a smart locker, then they use their smartphone to control their locker through integration with the EY My Day workplace experience mobile application. This allows employees to use just one user interface for storage booking, access, wayfinding and meeting room booking.

The better the world works

Reimagined workplaces that meet the needs of a hybrid workforce

Offices designed for hybrid workers need to include smart storage solutions.

Smart storage is a component of the technology ecosystem provided by  EY Workplace Reimagined , a service offered to clients that addresses the needs of the hybrid workplace. This system integrates with existing EY technology to improve the employee office experience. Smart lockers also provide valuable insights and data to aid decision-making for our facilities management teams.

“We previously had to collect the data around the utilization of the storage, such as how long it has been assigned, how frequently it is accessed, and whether we still have locked storage for people who are no longer at the firm, through manual processes,” said Philip Lynch, EY Americas Enterprise Support Services Leader. “Smart lockers provide us with that insight in real time, and then it can be part of a larger conversation about how we’re using the space and how we might improve. It’s not just optimizing for storage utilization, but also improving every facet of the workplace experience for all of our employees.”

The knowledge gained from the One Manhattan West implementation is defining the standards for other EY offices around the globe. Each new office coming online in the US will include smart lockers, and other offices that did not have this capability are being retrofitted because of the success of One Manhattan West.

The  EY Workplace Reimagined service offering  can help organizations through an ecosystem of integrated digital workplaces and smart building technologies that can benefit clients at all levels of digital workplace maturity. Workplace Reimagined also helps clients determine real estate footprint needs in each market and transform their use of space for meetings, interaction, collaboration, ideation and work with customers.

James and Jennifer Crumbley, a school shooter's parents, are sentenced to 10-15 years

(From left) James Crumbley, his attorney Mariell Lehman, Jennifer Crumbley and her attorney Shannon Smith sit in court in Pontiac, Mich., for Tuesday's sentencing on four counts of involuntary manslaughter for the deaths of four Oxford High School students who were shot and killed by the Crumbleys' son.

James and Jennifer Crumbley, whose son murdered four classmates and shot seven other people at Oxford High School in 2021, were each sentenced Tuesday in a Pontiac, Mich. courtroom to between 10 and 15 years in prison.

Both Crumbleys were found guilty in separate trials on four counts of involuntary manslaughter. Each of those charges carried a maximum penalty of 15 years, and the sentences are to be served concurrently.

In court, the Crumbleys looked visibly shaken, breathing heavily as they read from prepared statements prior to learning their fate.

James Crumbley spoke directly to the parents of the students his son had murdered. Several family members attended the sentencing.

"I am sorry for your loss as a result of what my son did," he said. "I cannot express how much I wish that I had known what was going on with him or what was going to happen. Because I absolutely would have done a lot of things differently."

James Crumbley, father of school shooter, found guilty of involuntary manslaughter

In her statement, Jennifer Crumbley said she, her husband and her son, Ethan, were an average family.

"We weren't perfect but we loved our son and each other tremendously," Crumbley said. "This could be any parent up here in my shoes. Ethan could be your child, could be your grandchild, your niece, your nephew, your brother, your sister. Your child could make the fatal decision not just with a gun but a knife, a vehicle, intentionally or unintentionally."

The teenagers who lost their lives during the shooting rampage were Justin Shilling and Madisyn Baldwin, both 17, Tate Myre, 16, and 14-year-old Hana St. Juliana. Six other students and a teacher were injured.

When it was time for their families to speak, several members described how the murders still haunted them.

Nicole Beausoleil, whose daughter Madisyn Baldwin was shot at point blank range, told the Crumbleys buying their son a gun when he was already spiraling into despair made them just as responsible as the shooter.

"Not only did your son kill my daughter but you both did as well. The words 'involuntary' should not be a part of your offense. Everything you did that day, months prior and days after were voluntary acts (helping) your son to commit a murder. Not just one, but multiple," Beausoleil said.

A rare prosecution

The Crumbleys are believed to be the first parents of a mass school shooter to have been charged and convicted of such crimes. Many legal experts say it could set a precedent for charging parents with serious crimes because of actions taken by their child.

Their son, Ethan Crumbley, pleaded guilty to murder and previously was sentenced to life without parole for the school shooting he carried out when he was 15.

Prosecutors never claimed the parents knew about their son's plans to go on a killing spree at Michigan's Oxford High School. However, they argued the Crumbleys ignored signs their son was seriously troubled and bought him a powerful Sig Sauer 9mm handgun as an early Christmas present.

They never told counselors about the gun they gifted their child when they were called to a meeting at the school the day of the shooting, not even when they were shown drawings the teen made. The images featured a pistol resembling the Sig Sauer alongside a figure with bullet wounds and phrases like "blood everywhere" and "help me, the thoughts won't stop."

Jennifer Crumbley convicted of involuntary manslaughter over son's school shooting

Instead, the Crumbleys left their son at school and returned to work. A few hours later, Ethan emerged from a school bathroom with the gun and began firing his first of 32 shots.

Prosecutors told the jury if the Crumbleys had taken a "tragically few steps," four Oxford students would likely still be alive.

They showed evidence that the murder weapon was never properly secured away from their troubled son.

In court, Oakland County Prosecutor Karen McDonald used the murder weapon to demonstrate how to use a cable lock to keep the gun from being fired.

The process took about 10 seconds.

A 'chilling' lack of remorse

The prosecution had asked for the Crumbleys to serve 10 to 15 years in prison, citing what they called a "chilling lack of remorse" on the part of both parents after the shooting.

Prosecutors noted that Jennifer Crumbley testified during her trial that "I've asked myself if I would've done anything differently. And I wouldn't have."

And they pointed to repeated profanity-laced threats James Crumbley made against Oakland County Prosecutor Karen McDonald on jailhouse phone calls he knew were being recorded, as well as in an electronic message.

'Mistakes any parent could make'

James Crumbley's attorney countered that his client had not physically threatened the prosecutor, he merely "vented" his anger over what he saw as an unjust incarceration.

The Crumbleys said they, too, were victims of their son, who they claimed had "manipulated" them into the purchase of a gun they had no idea he would use to kill.

They argued they made "mistakes any parent could make," given the information they had.

Defense attorneys for the couple noted an Oxford High counselor determined Ethan could remain in school the day of the shooting because he did not seem to pose a danger to himself or anyone else.

The couple maintained they thought their son was a normal teenager simply depressed over the loss of his grandmother, a pet dog and a friend who had moved away.

In a pre-sentencing interview with state officials, Jennifer Crumbley said that with the benefit of hindsight, "There are so many things I would change if I could go back in time."

Defense claims extra prison time unnecessary

The Crumbleys had asked to be sentenced to time served.

Defense attorneys argued the parents had already spent more than two and a half years in prison locked in a cell for 23 hours a day, and that further prison time was not necessary because the Crumbleys were not a threat to the public.

Defense attorney Shannon Smith also said more time would not deter others from committing a similar offense because "there is no person who would want the events of Nov. 30, 2021, to repeat themselves."

Smith added that, far from being the uncaring, remorseless mother prosecutors had portrayed to the public and the media, Jennifer Crumbley was focused on her son and distraught over the devastation her son caused.

In a sentencing memo, Jennifer Crumbley's parents and others pleaded with the court for leniency. A young woman, who said she was 18 when she became Crumbley's cellmate for a year and a half, also wrote to the judge.

She said Crumbley had greeted her with a basket of snacks and served as a mother figure to her.

The woman also wrote that inmates screamed threats at Crumbley, who tearfully told them she was sorry and "wished she could change everything her son had done."

Though Judge Cheryl Matthews sentenced the Crumbleys to the stiffest penalty possible, she said that the sentences were not designed to send a message to other parents or prosecutors that they should hold families responsible for children's crimes.

"These convictions are not about poor parenting. These convictions confirm repeated acts, or lack of acts, that could have halted an oncoming runaway train. About repeatedly ignoring things that would make a reasonable person feel the hair on the back of their neck stand up," Matthews said.

Moments after they were sentenced, the Crumbleys began filling out paperwork in the courtroom for an appeal.

Their son, Ethan, who pleaded guilty in October 2022 to murder and terrorism charges, is also likely to appeal his sentence of life without the possibility of parole.

New Englanders, with their love of seafood, may be at higher risk for PFAS exposure

• Sujata Srinivasan, Connecticut Public

A study from Dartmouth found that higher consumption of seafood is linked to a higher risk of  per-and polyfluoroalkyl substances (PFAS)  exposure. While the study looked specifically at people in New Hampshire, New Englanders are likely at higher risk because a legacy of PFAS pollution exists alongside a cultural preference for fish.

Researchers analyzed PFAS concentrations in fresh seafood with a statewide survey of eating habits in New Hampshire.  National nutrition surveys  have found that New Hampshire and all of New England are among the top consumers of seafood nationally, making New Hampshire ideal for researchers to learn more about the extent of people’s exposure to PFAS through fish and shellfish in saltwater.

“Basically, New Hampshire is a kind of case study that quantifies seafood consumption, particularly in a New England state, in order to estimate the potential risk of PFAS exposure that may come from very frequently consuming marine seafood,” Megan Romano, corresponding author and associate professor of epidemiology at Dartmouth’s Geisel School of Medicine, said.

She said the findings,  published in the journal Exposure and Health , make a case for setting PFAS limits on seafood, not to stop eating seafood.

"Understanding this risk-benefit trade-off for seafood consumption is important for people making decisions about diet, especially for vulnerable populations such as pregnant people and children," Romano said.

“New Hampshire was among the first states to identify PFAS in drinking water, according to Jonathan Petali, the study’s co-author and a toxicologist with the New Hampshire Department of Environmental Services.

“We're a data-rich state due to years spent investigating the impacts of PFAS and trying to mitigate exposure,” he said.

The researchers measured the levels of 26 varieties of PFAS in samples of the most consumed marine species: cod, haddock, lobster, salmon, scallop, shrimp, and tuna. The seafood studied was purchased fresh from a market in coastal New Hampshire and originated from various regions.

They found shrimp and lobster to contain the highest concentrations of PFAS with averages ranging as high as 1.74 and 3.30 nanograms per gram of flesh for certain PFAS compounds. Concentrations of individual PFAS in other fish and seafood measured less than one nanogram per gram.

The Environmental Protection Agency set the nation’s first limits on PFAS in drinking water Thursday.

“Drinking water contaminated with PFAS has plagued communities across this country for too long,” Michael S. Regan, administrator of the EPA, said in a statement. “ Our PFAS Strategic Roadmap marshals the full breadth of EPA’s authority and resources to protect people from these harmful forever chemicals.”

Studies have shown that women with exposure to PFAS may be at  higher risk of higher blood pressure , and  people with PFAS exposure  may have increases in cholesterol levels, decreases in birth weight, lower antibody response to vaccines, kidney and testicular cancer, pregnancy-induced hypertension, preeclampsia and changes in liver enzymes.
