Applied through on campus recruiting. Recieved first round interview. Two sets of one on one session, each were 45 mins long. Each discussing behavioral and one case. One interview focused on my resume and other focused on larger why BCG, why consulting kind of questions. Interviewers and recruiters were extremely friendly. Each case used multiple exhibits that aren't too simple. Overall interview was not too difficult.

Multiple rounds with consulting case interview portions and fit portions. Each round of interviews had multiple interviews, and the interviewer gets more senior as you progress through the interview process
