I applied online. The process took 2 weeks. I interviewed at Bain & Company (New York, NY) in Oct 2015
Interview
Interviewers were very nice and helped guide me through each problem. Current ACs reached out to help prep and gave a lot of great insight. Make sure that you have market sizing down, otherwise it is a tough process. No behaviorals at all in the first round, so make sure you have done practice case interviews beforehand.
2 cases for R1. Pretty straightforward cases about revenue optimization opportunities. There was a little bit of market sizing but all data needed was given. No behaviorals asked in round 1 for me.
Interview questions [1]
Question 1
What office did you choose and why? Do you have competing offers?
2 rounds, 1st round 2 small cases, not very difficult , market entry cases.

Three rounds of interviews, generally 2 rounds in person or remote with live consultants. Each round involves a 2-3 case interviews each, which generally also include a set of behavioural questions.
