Application, 2 rounds of interview. It's very much about how well you fit the "image" of a consultant, and whether you can think on your feet. The way you answer questions is as important if not more so than what answer you provide. Bain was pretty open culturally and I appreciated that.

Interviewers were really nice, but the process was difficult. Standard level cases and they expected you to take them through multiple business problems. If you practice casing frequently with multiple partners, you should be fine.
