The process took 2 weeks. I interviewed at McKinsey & Company (Chicago, IL) in Nov 2011
Interview
I was an APD candidate and took a 26 question multiple choice test. Then there were breakout sessions with 4 other candidates and a current consultant to work through cases as the case interview was unfamiliar to many of us. It was an odd experience and our invitation for a second interview was based solely (or so they say) on our performance on the 26 multiple choice questions. The word questions were not overly complex but they involved a lot of calcuations and you are not allowed a calculator. Work on basic mental math before you interview!
It was an odd way of being judged and the day I was informed I would not be invited for a second interview I heard an NPR piece on a former McKinsey big muck who was indicted on multiple counts of insider trading.
It was a one-to-one interview with a consultant. It's a typical case study. The experience was traumatizing. I know my answers weren't great, the consultant was elegant and didn't bother to hide his boredom.
