The process took 1 day. I interviewed at McKinsey & Company in Jan 2011
Interview
I had 2 hourlong interviews. Each consisted on 1 behavioral question and a case. The behavioral questions were very general and the interviewer asked lots of follow-up questions on my answer. Then we moved on to the case. Compared to other consulting cases, McKinsey's tend to be more specific (i.e. they give you more data without you having to probe for it). I definitely failed to "crack" one of the cases, so I wasn't surprised not to get an offer.
After the interview, one of my interviewers called me and provided very specific feedback--basically to go more in depth with the case (from my base framework, create 4-5 bullet points under each broad category).
On campus, met with three different partners/associate partners. Behavioral question followed with case. Behavioral interview they were fishing for something very specific in the story and more often than not I didn't even get to the end of what I prepared.
Case was much shorter than Case Book examples. They take your scrap work so make sure it's clean.
1)Framework (MECE is very important to them)
2)Insights from Graph (Important to hit 3rd level insights)
3) Math Calculation (Math wasn't complicated but had many coponents, organization is key)
Interview questions [1]
Question 1
Tell me about a time where you handled a conflict with a coworker
Long and hard. Overall, the people were really nice, but one of the partners in my very last interview gave me a very difficult time with one specific chart. The cases were much harder than I had actually prepared for.
I applied online. I interviewed at McKinsey & Company in Jan 2026
Interview
It consisted of three case interviews and a personal experience interview question. Mine were in one day back to back. The PEI was pretty standard. the case interviews were difficult.
