I was contacted by a recruiter, who guided me through the process. For the most part, the process was straightforward, but the company came across as unorganized and disrespectful. I went through a CV screen and a more informal chat with a recruiter as well afterwards about my experience. These were good and fine, and then moved forward to a Round 1 interview. First issue: BCG re-scheduled my R1 interview 6 different times. They even emailed me at ~4pm, asking if I could move my interview up to the following morning at 8am. I said no, and was able to interview further out. Secondly: On the day of my R1 interview, about an hour before the interview, they pushed it back a little bit and shortened it from 60min to 45min. Third: When the interviewer called into the interview, they were walking into an elevator. After being disconnected, they called again from the parking lot and conducted the entire interview, camera off, while driving. Fourth: The feedback I received reflected information that was inaccurate, which I had clarified multiple times with the interviewer (who was driving). I followed up in writing afterwards to clear up the confusion. Further, one glance at my resume would have cleared up my experience, or a chat with the recruiter who conducted the CV screen and verified my information.

Different steps with business case analysis, on topics more or less known to the candidate. Embarrassing the arrogance of the managers who do the interview, who give wrong answers to their own questions.
