Hi!
It depends on the specific role and practice you are applying to, and the company of course.
I would expect most of your cases to be in the life science industry, especially if you are applying for a practice where you know you are going to work 100% only on life science projects. E.g., a lot of risk consultants are hired to work 100% only on risk projects, thus being tested mainly on those skills.
On the contrary, if your role will define you as an expert in life science, but you may have to work occasionally in other industries, this will increase the probability of you having non-life science cases during the interviews.
As a final remark, the skills tested in consulting interviews usually go beyond sector-specific knowledge (e.g., analytical thinking), so I would always advise to be prepared to handle different topics.
I hope this helps!
