The process took 3 weeks. I interviewed at McKinsey & Company (New York, NY) in Jan 2012
Interview
Exactly as described online; PST + 2 case interviews (1st round) + 3 case interviews (2nd round). Spend as much time preparing for the behavioral portion as you do for cases.
Cases were slightly longer than other firms, and the 2nd round cases were harder.
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)

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.
