Got an on campus interview by applying online to both the McKinsey website and our campus recruiting website. A week before the interview, McKinsey hosted a case interview workshop, during which BA's gave us tips on the process and split us up into groups for a practice case. This was super helpful, given it was the first case interview I have ever experienced. I also found potential study buddies. The first round interview was on my college campus: one-hour interviews with two Engagement Managers each, 15 minutes devoted to Fit and 45 minutes devoted to the case. My interview was Friday, and on Monday, the recruiter called to let me know I had a second final interview in two weeks. At this point, tons of people from McKinsey e-mailed me to congratulate me in getting a second interview and offered to either grab coffee or review cases with me. My first round interviewer called to give me feedback on how I can improve, which was incredibly helpful. I was very touched and amazed by the support I received from McKinsey at this point. My final interview was on-site at the office I applied for. The night before, all the applicants had dinner with current BA's, which was really fun. Again, the final interview was standard, this time I was interviewed by 2 partners a 1 associate principal. The interviews were from 8-11am, and by 1pm a partner I interviewed with called to tell me I had an offer. That night, all offerees were invited to celebrate. I had a blast interviewing with McKinsey, and very much appreciated the professionalism of the company, the support they gave interviewees, and the enthusiasm the people in the company had for their jobs.
