I applied through college or university. The process took 3 weeks. I interviewed at Bain & Company (Dallas, TX) in Sep 2016
Interview
Had my first round on-campus with managers and consultants. Found out I got a final round the next afternoon. Final round was one week later at the office, with a dinner with alumni the night before. Interviews at the final round were with partners. Same level of difficulty, assuming you've done the prep and are comfortable with case interviews
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.

Question 1
What office did you choose and why? Do you have competing offers?

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.
