I applied online. The process took 2 months. I interviewed at Bain & Company (London, England) in Oct 2021
Interview
Round 1: market sizing + case + behavioural interview
Round 2: 2x oral cases + 1x written case
Cases are standard, interviewee-led consulting cases; written case involves ~30 pages of materials to review and ~45 mins prep time before a ~15 mins presentation
Interview questions [1]
Question 1
Behavioural: what would you do if someone on a case for one of your client's competitors gave you information you shouldn't have about the competitor?
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.
