THE CASE INTERVIEW
Case interview overview
The case interview is at the core of the consulting interview process and is probably the most intimidating element. Start by watching this video to understand case interviews and how they are assessed.
How to prepare
You’re trying to join some of the most selective employers in the world. Unfortunately, case interviewing skills are not innate. In this video, we'll explain the preparation that it takes to land your dream job.
What makes a good structure: the AIM Test
Structuring is perhaps the most challenging dimension of a case. In this lecture, we’ll tell you what structuring is and use the AIM test to describe what makes a good one.
How to build it
In a typical case interview, you only have 60 to 90 seconds to come up with a structure, and it's often about a question that you’ve never thought about before. In this video, we’ll discuss how you can go about successfully structuring a case in this short period of time.
Top-10 business frameworks
Many cases are based on the business problems that senior executives are likely to face during their time at a company. Every candidate should know how to address these problems. In this lecture, you'll learn the top-10 frameworks that do just that.
Academia has produced a number of frameworks to think about business strategy. In this video, we'll look at the three academic frameworks that will best help you structure cases.
Learning and applying standard frameworks alone won’t work. We’re seeing more and more case interviews involving unusual case types. Watch this video to explore logical approaches that will help you craft bespoke structures to the most atypical case questions.
How to communicate your structure
How you communicate your structure is equally as important as the structure itself. In this video, we’ll discuss how you can most effectively present your structure to your interviewer.
How to solve numerical questions
Being proficient with numbers is essential to handling case interviews successfully. Watch this video to understand how numeracy is assessed and learn techniques about how to do well on this critical dimension.
How to spot insights
Judgement & insights is one the most qualitative problem solving dimensions tested in a case, and it is often done through the interpretation of exhibits and charts. Watch this video to learn how to handle these questions and the types of charts most often seen in case interviews.
How to generate ideas
Creativity is one of the best ways to stand out against other well prepared candidates. Watch this video to learn how creativity is assessed and how to avoid running out of ideas in the middle of a case.
How to lead the case
In a case interview, you are expected to play the role of a consultant leading a problem-solving discussion with a client. Watch this video to learn about case leadership and the art of driving a case-based conversation.
How to synthesize your findings
Providing a clear recommendation at the end of the case discussion is critical to cracking a case and leaving a positive final impression to your interviewer. Watch this video to learn how to deliver a convincing, concise and fact-based conclusion and close any case interview successfully.
ALTERNATIVE CASE FORMATS
Estimations and market sizing
Estimation and marketing sizing questions come up frequently as part of broader cases. Occasionally, firms will use them as a standalone exercise instead of a case. In this video, we will describe the format of these questions, reveal how they are assessed, and share our tips to nail them.
Written cases are increasingly used by firms, and are by far the most difficult and selective exercise you might face. In this video, we will describe how written cases work, why so many candidates fail, and how you can succeed.
THE FIT INTERVIEW
Fit interview overview
The fit interview is half of the assessment and often makes the difference between getting an offer or not, but it's too often overlooked by candidates. Start by watching this video to understand fit interviews and how they are assessed. Then watch the model fit interview (Enguerran) in conjunction with the interview scorecard, so you can see how it plays out in real life.
How to introduce yourself
The ability to introduce yourself effectively will set you up for a successful fit interview and will directly affect your ability to build rapport with your interviewer and demonstrate top performance. Watch this video to learn how to introduce yourself effectively in a fit interview.
How to present your motivation
You'll very frequently receive questions about why you're looking to do consulting and why you are interested in the firm you're interviewing with in particular. Watch this lecture to learn how to demonstrate your motivation.
How to pitch an achievement
In a full fit interview, or in a Personal Experience Interview at McKinsey, you will be asked to talk about your achievements and to demonstrate that you have the right abilities for the job. In this section, you will learn how to demonstrate the transferable abilities that the firms are seeking in candidates.
GET THE OFFER
How to look right on the day
The day has finally arrived! You don’t want to stand out for the wrong reasons. In this video, we share a few final comments about how to look the part on the day of your interview.
How to stand out
Now you should have a good grasp of the attributes that top consulting firms look for and how to demonstrate and build up those attributes. However, top firms don't need to hire every candidate who ticks all the boxes. They have the luxury to choose only those who excel above the rest, so the question is: how can you stand out and get the offer?
Addition is probably the simplest of the four operations. But it can still be a cause of errors in a case interview when performed in the head. In this lecture, we'll walk you through the basics of pen-and-paper addition, both with whole numbers and with decimals.
It has probably been a while since you've subtracted the kind of large numbers that you're going to see in cases. In this video, we'll refresh your memory and show you how to subtract large numbers.
Multiplication is the most frequent of the four operations that you'll encounter in a case interview. Watch this video to learn the basics of multiplying on paper for whole numbers and decimals.
Division is undoubtedly the hardest of the four operations to perform, whether in your head or on paper. In this lecture, we'll walk through the basics of long division, for whole numbers and with decimals.
Case interview math often involves fractions rather than whole numbers. Watch this video to learn the basics of fractions, including simplifying fractions, the four operations with fractions and shortcuts to find common factors.
Most business metrics are expressed as percentages (e.g., gross/net margin, ROI). Calculating with percentages is therefore an essential key math concept to master. In this video, we'll introduce percentages, teach you how to convert percentages and fractions, and how to multiply percentages.
Compounding comes handy if you are looking to project the future revenue of a business, or the future value of an investment. It is commonly featured in case interviews. Watch this video for a walkthrough of simple growth rates, and compounding.
An organization's performance is often summarized by one overall metric, whether it is sales or profit. This requires aggregating different segments, such as product lines or distribution channels, using a weighted average. We'll cover this concept, as well as simple averages, in this lecture.
Organizations often make decisions based on uncertain outcomes. That’s why a basic understanding of probability is critical to making business decisions, and to ace case math. Watch this video to learn how to work with probability and how to compute expected values.
In most cases, laying a clear and optimal approach to solving a math problem requires writing an equation. In this lecture, we'll walk you through how to create an algebraic equation and how to solve it.
Keeping track of zeros
To stand out against other candidates, you'll need to solve problems quicker and more reliably than others. The number one math mistake that we observe in case interviews is miscounting zeros. In this lecture, we'll explore three methods to keep track of zeros and avoid this pitfall.
Simplifying calculations with distributive properties
The secret to being fast and reliable in case math, and to impress your interviewers, is to make life easier for yourself by simplifying your calculations. In this lecture, we'll cover the distributive property in multiplications and divisions and how you can use it to simplify your calculations.
Simplifying calculations with factors
While we have taken a brief look at factors in our lecture on fractions, factors have much wider applications in the simplification of operations involving large numbers. Watch this video to see how to simplify case math using factors.
Simplifying calculations with rounding
Case interviews typically call for decision making which requires directional accuracy rather than scientific precision. This makes rounding an invaluable tool for simplification when making assumptions or within calculations. In this video, we'll take a close look at simplification with rounding.
Fraction values to remember
Some fraction values are used so often in case math that knowing them, their percentage value and their decimal conversions can save you significant time. Watch this video for an overview of the most used fractions and download the accompanying summary for easy reference.
The majority of case interviews focus on helping a company achieve better financial results. These results are tracked with financial statements. In this lecture, we'll take a close look at the income statement, the most widely used financial statement in case interviews.
While not referenced as much as the income statement in case interviews, the balance sheet carries important information about a business and works hand in hand with the income statement. In this video, we'll cover what you need to know to ace balance sheet-related questions in case interviews.
It is rare to come across a cash flow statement in a case interview. However, a basic understanding of cash flow concepts can come handy. These include the types of cash flow, how cash flow differs from profit, and the concept of working capital. These concepts are discussed in this lecture.
Many cases are focused on whether a company should make an investment. To handle these questions, it is important to understand the analyses typically performed ahead of investment decisions. In this lecture, we'll cover how to calculate break even, Return On Investment and payback period.
Although you'll very rarely be asked to value a business in a case, understanding valuations may help you structure your approach and understand exhibits in relevant cases. Watch this video to learn simplified versions of key valuation methods such as Comparables and Discounted Cash Flow.
Many businesses operate a process to produce a standardized good or service. Some case interviews are based on optimizing such processes. In this lecture, we'll briefly cover the core operations concepts of capacity, utilization and efficiency.
