You might receive an industry-related case, but you should prepare for unfamiliar sectors as well.

Case selection differs by interviewer and process, and prior expertise does not guarantee or exclude a particular industry.

A healthcare executive may get a retail growth case where clear questions and commercial reasoning matter more than prior facts. Senior candidates may face tougher probing of judgment and leadership even where the case mechanics are similar.

Practice unfamiliar industries so you can distinguish facts given in the case from assumptions carried over from work. Review the types of consulting cases to broaden your exposure instead of relying only on sectors you know.

I'd be more nervous about a case in my own industry, oddly.

My industry assumptions could actually get in the way.
