Preparing Case Studies for Interviews in Consulting Jobs

A case interview is a job interview where you, as a candidate, are expected to analyse and solve a business scenario (“case study”). This interview format, which is meant to be a simulation of the real world, is used by employers to evaluate your analytical and communication skills.

Case interviews start with a brief introduction and small talk. Next is a personal fit segment, covering your background and motivations. The main part is a business case to solve. The interview ends with your questions for the interviewer.

One of the main reasons why most management consulting firms have adopted the case interview format as a standard practice is that the topics and themes dealt with in most cases are very close to the consulting reality. The applicant is required to ask the right questions, use structured frameworks, and come up with creative solutions. As a consultant, you are going to be in direct contact with the client for the majority of the time; hence, the interviewer considers that your soft skills are just as important as your hard skills. Why do they try to assess your performance in a case interview? The question that is asked by hiring companies through the case interview is: “Would I be able to be comfortable showing this candidate to the client?” 

Ways to Differ from Others at the Case Interview:

1. Going through your work while talking to yourself is definitely a good thing. In case you still don’t understand what the problem is, it might be a good idea to take some time and simply get acquainted with the data. Whenever your problem leads you to a dead end, try to find another perspective. Don’t let your situation get the best of you; rather, use your brain to find a way out of it.
   
   
2. Always, never give up on questioning. It is quite all right if you ask the interviewer to clarify an acronym or to repeat or confirm details. If the interviewer leads you to the question, “How do we achieve success?”, don’t hesitate to answer, “Would you please explain what ‘success’ is? Is it making more money? Increasing the company’s popularity?” If you are working on a client project and have questions, you definitely ask them to clarify the problems, and this case is no different. The interviewer is the most important person in the room. They are the ones who, in fact, hold the keys that open the door to “successfully solving the case”. So, don’t waste your time with them, but be smart and wise!
   
   
3. It’s too good to be true if your stubbornness with the plan is saving you. The case study interview topic might be changed by the interviewer. In such a case, it is advisable that you prepare yourself to be led by the interviewer’s instructions. The way your previous experience is discussed might be limited to only half of the interview, after which they will proceed with the case, or the interview might be initiated with the case, followed by questions about your experience. To be clear: It is important to be versatile and willing to discuss your job and the manner in which you carry it out.
   
   
4. Make your presentation more effective with the help of visuals. If it is through the use of a pen and paper that you organise your thoughts by drawing them out, and by explaining the problem to someone, you help yourself with the case, so just do it. The only thing that is most important is to demonstrate that you have problem-solving skills.
   
   
5. Be impact-focused. First, take a look at the data that you have, and then do what will create the greatest effect. Keep track of your thought process and don’t forget to tell it as well as your assumptions.
   
   
6. Tell a story. Your experience has been the vehicle that took you along your career and educational journeys; hence, you should make use of that experience. For instance, while handling a business case study of the airline industry, you could weave the story of yourself as a traveller. Being human is of great importance. When you are different, you have that certain thing that provides special insights, and it will be to your benefit during the interview.
   
   
7. Be extremely watchful of the hints. Most of the time, when the interviewer utters a certain thing, it is probable that it implies something. Don’t just ignore the details that are there but seem to be of no importance. As an example, the interviewer might say, “The case is about a retailer who wants to increase the value of a company purchased, and the owner who loved the brand when growing up.” The detail’s purpose here is to show that selling as a way of making the asset profitable is not an option because the owner is emotionally attached to it.

Four Common Types of Questions in Consulting Interviews

Firstly, the four common types of questions in case interviews are:

• Ice-breaker questions
• Fit behavioural interview questions
• Case interview questions
• End-of-interview questions

Remember that these four types of questions do not encompass all the possible questions in consulting interviews. Some of these questions are quite general (e.g., the ice-breaker questions), and thus senior/experienced consultants are more likely to ask you the less predictable questions. A candidate must think, speak, and act like a consultant if he/she want to impress the interviewers.

What interviewers Look for in Interviews

Problem-Solving Skills:

The Consulting industry as a whole is based on the idea that consultants are the ones who can break down business problems better than anyone, so this attribute is a must.

Leadership Skills:

Convincing a group of highly experienced people (your clients) to do something they don’t want to do is, of course, not very easy. Besides, consultants normally work in teams – leadership here means being able to influence others rather than getting voted as the class monitor.

Achieving Mentality:

The issues, as a rule, will be enormous and complicated, and the time available for solving them will be very short. Don’t work-life balance into your thoughts even; it’s an all-or-nothing game.

On the other hand, business background and technical skills are not as necessary, but it would be great for a candidate to have them. These two give the candidate a great advantage, so by all means, demonstrate them as much as you can.

Business Background:

It is not a prerequisite for a candidate to be a business major to become a prospective consultant; however, business knowledge is crucial for excellent performance in case interviews. Fortunately, it is something you can learn, and most of the concepts used in consulting interviews are just at the basic or intermediate levels.

Technical Skills:

These skills are necessary for specialist roles, for example, at McKinsey Digital. However, the required expertise or technical  knowledge

Conclusion

Passion is the main quality that consulting firms identify and value most, according to the companies they consulted. This essentially means that one has to demonstrate involvement, liveliness, and curiosity with the issue being discussed and the way of solving the problem. It is important to note that the person who interviews you is most probably a person who is in charge of consulting projects daily (‘Job Manager,’ ‘Engagement Manager,’ ‘Senior Associate’), thus, like in all interviews, one of the decisions they will be making is if you are the kind of person they would like to have in their team or not. Generally, the time that you have at your disposal is quite limited, and it is not feasible to display all of your analyses and hypotheses. Hence, you ought to concentrate your efforts chiefly on providing answers to the key questions as they influence your proposal to the greatest extent.
