I applied through a recruiter. The process took 3 days. I interviewed at McKinsey & Company in Aug 2009
Interview
The interviews were very structured, with the cases being fairly linear, with the interviewer "leading" me towards a solution. Practicing mental arithmetic was a big part of my success here I think.
The experiential bit was not difficult with preparation - get your stories straight with a lot of "I did x" or "I said y" parts.
2 interviews back-to-back in-person. Cases weren't super hard but you definitely need to prepare a lot beforehand to navigate the curveballs and be able to function under high stress. Expect difficult industries and focus on PEI which is half as important.
Interview questions [1]
Question 1
Tell me about a challenge situation that you faced in detail (expect to be interruped because they will go deep into the story, make it memorable and interesting)
