How to Crush Your Life Sciences Consulting Case Interviews

If you’re interviewing for a life sciences consulting firm, expect to be given several case interviews, or case study interviews, during your interview process.


A case interview is a special type of interview that nearly every single consulting firm uses, including life sciences consulting firms. Firms that use case interviews include: Clearview Healthcare Partners, Putnam Associates, IQVIA, ZS Associates, Simon Kutcher, and Health Advances.


Case interviews simulate the consulting job by placing you in a hypothetical business situation in which you are asked to solve a challenging problem. These interviews typically last between 30 to 45 minutes and you’ll be working closely with your interviewer towards developing a recommendation or answer to the business problem.


Case study interviews are so widely used by life sciences consulting firms because they assess many of the qualities needed to become successful consultants. With just a 30- to 45-minute exercise, an interviewer can gauge your analytical capabilities, business acumen, communication skills, and cultural fit with the firm.

Telemedicine: Progress in telemedicine is one of the biggest sources of substantial change in the healthcare ecosystem. It is improving the quality of diagnosis and treatment by allowing patients to get proper access to healthcare professionals.


The 6 Steps to Solve Any Life Sciences Case Interview


There are typically six steps to solving life sciences consulting case interviews.


1. Understand the case


Your life sciences case interview will begin with the interviewer giving you the case background information. While the interviewer is speaking, make sure that you are taking meticulous notes on the most important pieces of information. Focus on understanding the context of the situation and the objective of the case.


Don’t be afraid to ask clarifying questions if you do not understand something. You may want to summarize the case background information back to the interviewer to confirm your understanding of the case.


The most important part of this step is to verify the objective of the case. Not answering the right business question is the quickest way to fail a case interview.


2. Structure the problem


The next step is to develop a framework to help you solve the case. A framework is a tool that helps you structure and break down complex problems into smaller, more manageable components. Another way to think about frameworks is brainstorming different ideas and organizing them into different categories.


Before you start developing your framework, it is completely acceptable to ask the interviewer for a few minutes so that you can collect your thoughts and think about the problem.


Once you have identified the major issues or areas that you need to explore, walk the interviewer through your framework. They may ask a few questions or provide some feedback.


3. Kick off the case


Once you have finished presenting your framework, you’ll start diving into different areas of your framework to begin solving the case. How this process will start depends on whether the case interview is candidate-led or interviewer-led.


If the case interview is a candidate-led case, you’ll be expected to propose what area of your framework to start investigating. So, propose an area and provide a reason for why you want to start with that area. There is generally no right or wrong area of your framework to pick first.


If the case interview is interviewer-led, the interviewer will tell you what area of the framework to start in or directly give you a question to answer.


4. Solve quantitative problems


Life sciences case interviews may have some quantitative aspect to them. For example, you may be asked to calculate a certain profitability or financial metric. You could also be asked to estimate the size of a particular market or to estimate a particular figure.


The key to solving quantitative problems is to lay out a structure or approach upfront with the interviewer before doing any math calculations. If you lay out and present your structure to solve the quantitative problem and the interviewer approves of it, the rest of the problem is just simple execution of math.


5. Answer qualitative questions


Life sciences case interviews may also have qualitative aspects to them. You may be asked to brainstorm a list of potential ideas. You could also be asked to provide your opinion on a business issue or situation.


The key to answering qualitative questions is to structure your answer. When brainstorming a list of ideas, develop a structure to help you neatly categorize all of your ideas. When giving your opinion on a business issue or situation, provide a summary of your stance or position and then enumerate the reasons that support it.


6. Deliver a recommendation


In the last step of a life sciences case interview, you’ll present your recommendation and provide the major reasons that support it. You do not need to recap everything that you have done in the case, so focus on only summarizing the facts that are most important.


It is also good practice to include potential next steps that you would take if you had more time or data. These can be areas of your framework that you did not have time to explore or lingering questions that you do not have great answers for.

Life Sciences Consulting Case Interview Tips


Tip #1: Start preparing early


Mastering case interviews takes time. Many of the skills and techniques needed to solve case interviews can’t be learned in just a day or in a week. Ideally, start preparing for your case interviews at least a month or two in advance to give yourself enough time to learn and practice.


Tip #2: Practice with a case partner


Practicing case interviews with a partner is the best way to simulate a real case interview. There are many aspects of case interviews that you won’t be able to work on if you are doing mock cases by yourself. Casing with a partner lets you practice your communication, presentation, and collaboration skills.


Tip #3: Keep a list of feedback from each case


You should keep a journal or log of all of the different pieces of feedback you get from your case interview partner during practice. This way, you’ll be able to identify trends and prioritize what improvement areas to focus on. For example, if you consistently receive feedback in each practice case that you need to structure your answers, that should be your top area to focus on.


Tip #4: Focus on improving one thing at a time


After doing some practice case interviews, you’ll likely have a long list of feedback and improvement areas. Try to focus on improving one thing at a time. Before each practice case, decide on the one thing that you really want to focus on and nail. This will be much more effective than trying to improve everything at once.


Tip #5: Use a hypothesis-driven approach


During the case interview, you should have a hypothesis of what the answer to the case is. A hypothesis is simply an educated guess based on the knowledge that you have. As you analyze data and gather more information, make sure to be constantly changing and refining your hypothesis.


There are two benefits to using a hypothesis to drive the direction of the case. One, it ensures that you are focusing on relevant areas that will help you solve or answer the case. Two, by the time the interviewer asks you for a recommendation, you will already have a refined hypothesis on what the answer or solution to the case should be.


Tip #6: Be 80/20


You have limited time during a case interview to solve the case. Therefore, you won’t be able to cover all of the different areas in your framework and get answers to every single question that you have. Therefore, focus on the most important issues and use the 80/20 principle.


The 80/20 principle states that 80% of the outcome comes from 20% of your effort. During a case interview, focus on the most important questions or areas that will have the biggest impact or effect on developing your answer or recommendation.
