It was a first and final round. The first round was two 45-minute interviews with a case and behavioural portion. It was a different interviewer for each part. The behavioural questions differed from both interviewers.
One robot interview. First round. Then two final rounds back to back. It got increasingly difficult but there was nothing unexpected. The case interview was not that difficult. If you study for at least 3 months, you should have good success.
I applied online. The process took 4 weeks. I interviewed at Boston Consulting Group (Chicago, IL) in Aug 2023
Interview
I felt the interview process was very fair. The interviewers, two partners at the firm, was extremely approachable and made the whole process quite comfortable. The fit portions were very standard questions, and it felt very conversational. If you know your resume, there should be no issues. The first case was quite straight forward, but the second was a bit more niche and threw me for a loop.
