I applied through college or university. The process took 2 weeks. I interviewed at Bain & Company (Los Angeles, CA) in Sep 2015
Interview
The interview process consists of 2 case interviews, each 30 minutes. At first there are some straightforward behavioral questions then proceeds to the case. It involves market sizing so you should be able to quantify everything and calculate everything on top of your head. Also, it includes profitability problem and market entry.
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.
