I applied online. The process took 5 weeks. I interviewed at Bain & Company (London, England) in Dec 2016
Interview
Applied online, did relatively simple online test. First round consisted of 1 case interview and 1 competency + market sizing interview (both ~35-40 minutes). Final round was one "interactive written case" and two case interviews with managers/partners. Was told after first round that if you are doing well they are likely to push you with off-the-cuff challenging questions.
Interview questions [1]
Question 1
Tell me about a time you had to deal with a conflict?
Market entry, profitability, and growth cases.
Written case involved going through ~30 slides of info and presenting findings, involved filling in a table of data which required many calculations.
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.
