Applied through my university. I heard back a week later and had a week to prepare for my back-to-back interview. They were two 30-minute case interviews. The first 5 minutes of each had general questions like "Why consulting?" "Why Bain?" But the bulk of the interview was case interviews. First case was with a Junior Consultant, the second case was with a Senior Consultant. This was my first consulting interview, so I didn't really expect to get it... But the cases had way more math than I anticipated. The interviewers were really nice though and were good at helping you steer your way through the case without being dicks about it. I do think the Junior Consultant "helped" me too much though. He didn't give me any time to think it through, while the Senior Consultant gave me time and let me talk out my thoughts before steering me in a certain direction.

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.
