Charles River Associate Life Science consultant

Here is what I would tell you as someone who has seen a lot of scientists make this transition.

CRA is different from MBB. Their cases are more technical and rooted in actual life science problems. Think drug pricing, market access, clinical trial strategy, competitive landscape for a specific therapeutic area. So generic case prep will only get you part of the way.

For a complete beginner, start here:

• Get comfortable with basic case structure first. You do not need to master every framework. Just learn how to break a problem into parts and work through it logically.
• Then shift to life science specific scenarios. Practice questions like: should this pharma company launch in this market? What is the commercial potential of this drug? How would you assess the competitive landscape for a biosimilar? CRA leans heavily in this direction.
• Your research background is your biggest asset. Do not hide it behind generic consulting language. CRA is hiring you because you understand science. They want to see you take that scientific thinking and apply it to a business problem.

One thing most scientists get wrong in these interviews. They go too deep into the science and forget to land a clear "so what." CRA wants to see you can translate complexity into a recommendation a client can act on. Practice that specifically.

Also, reach out to people already at CRA on LinkedIn. Most life science consultants are happy to chat because many of them made the same transition. A 15 minute conversation will tell you more than any prep book.

Hope this helps, and good luck with the process.

It's great you've landed that CRA interview – transitioning from research is a path many take, and firms like CRA truly value that deep scientific expertise. For your first round, especially coming from a research background, they're not necessarily expecting you to be a case interview master right out of the gate.

What they are looking for is your ability to structure ambiguous problems, think logically under pressure, and apply your scientific intuition to business challenges. While general guides like Case in Point are solid for understanding core frameworks, your critical next step is finding life science-specific cases. Focus on common industry scenarios: market sizing for a new therapeutic, competitive landscape analysis, R&D portfolio prioritization, or commercial strategy for a medical device. Practice articulating your thought process clearly, translating complex scientific concepts into actionable business insights.

The best way to get up to speed quickly is to practice cases out loud with others. Look for practice partners who understand the life sciences context – often you can find them through university career centers, LinkedIn groups, or even former colleagues who've made similar transitions. Their feedback on how you frame problems and communicate your solutions will be invaluable.

Good luck with the prep and the interview!

hey there :)

First of all congrats, that’s such an exciting step. CRA life sciences cases are usually more focused on pharma, biotech, pricing, market access, clinical strategy or portfolio decisions rather than generic profitability cases. As a research scientist you actually have a strong advantage on the content side, you mainly need to practice structure and business thinking.

For complete beginners I’d start with the basics using Victor Cheng or PrepLounge to understand how to structure cases and think hypothesis driven. Then specifically look for pharma and healthcare cases on PrepLounge. Also check sample cases from firms like LEK, ClearView Healthcare Partners and Putnam Associates, they are very similar in style to CRA life sciences work. Practice sizing patient populations, thinking about peak sales, competitive landscape, regulatory risk and reimbursement dynamics.

In the interview they will test how you translate scientific knowledge into commercial implications, so always ask yourself what does this mean for revenue, cost, risk or timeline.

If you’d like, tell me your background and target office and I can give you more tailored advice. You’ve got this :)

best,
Alessa :)

Happy to provide a perspective since I've worked with lots of life sciences candidates.

First of all, check with the recruiter to confirm whether the cases will be life sciences-focused or can be from any industry. This will enable you to focus your prep effectively. 

Second, consider a professional diagnostic. Typically, when I run this with my candidates, the outcome is a clear overview of their strenghts (and how to turn them into spikes), areas of development (and how to close the gap to being interview ready), a list of the highest impact 2-3 changes they should make, tailored drills and a readiness plan. Having something like this ensures every minute you put into your prep actually moves the needle.

Best,
Cristian

Hi there,

I suggest doing a few cases on your own and then one with a coach to help identify which areas you should focus on most in your preparation. This would ensure that you're being efficient with your time.

I also suggest clarifying with HR whether the cases are focused on life sciences. This will also help you be more targeted in the type of cases you practice with.
