I had two case interviews on campus with associates from Bain. They were very helpful and friendly and mostly guided me through the interview. First case was on the groceries industry, and second was on used-phones. Quite esoteric, but not unfamiliar markets to a typical college student. The math required was not very demanding. Second round was with two analysts and a partner in the Bain SF office. The partner usually has the shortest and easiest case, but also asked a couple behavioral questions (Why Bain? What do you want to do in the future? What interests you? etc.)

Really smooth and clear. Was supported at every stage and felt like I could clearly demonstrate my skills. Found the casing harder than expected but behaviorals were genuinely interesting to answer.
