INTRODUCTION

05:13

THE CASE INTERVIEW

10:46

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.

03:52

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.

13:24

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.

10:28

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 it successfully structuring a case in this short period of time.

26:01

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.

05:05

Academic frameworks

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.

07:19

Logical approaches

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.

04:34

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.

16:08

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.

01:53

Additions and subtractions

It’s probably been a while since you've added and subtracted the large numbers that you're going to see in cases. In this video, we’ll refresh your memory and give tips on how to quickly add and subtract large numbers on paper.

11:33

Multiplications and divisions

You're going to have to do multiplications and divisions in almost all cases. Watch this video to find out how to do these operations on paper.

05:10

Fractions and percentages

In business, people often use percentages, but calculations are so much simpler in fractions. In this video, we’ll remind you how these number forms work and how to convert between them.

11:24

Algebra

In many case interviews, you're going to need to make a formula and solve for missing variables. In other words: algebra. In this video, we’ll cover how to create your own algebraic equations and solve them.

05:04

Probabilities and expected values

Probabilities and expected values are essential business math concepts that often show up in case interviews. In this video, we will discuss how they work and how they can be applied to basic business problems.

16:20

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.

05:44

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.

11:20

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.

04:56

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

24:22

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.

22:54

Written cases

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

07:22

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.

12:47

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.

05:38

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.

14:54

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

02:50

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.

05:17

How to stand out

Thank you for watching these videos. 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?
