Applied online and was contacted by a recruiter a few weeks later. Overall process is HR Screen --> Practice Phone Case --> Actual Phone Case --> In Person Round 1 --> In Person Day 2. After the initial screener to make sure you're a fit for the position and vice versa, I was scheduled for the first round of phone interviews. A quick aside, I was told that the interview process is the same exact process as the standard Consulting process, so this is probably all one in the same. Anyway, the first step was a phone case interview with a McK alum that also comes with 1 on 1 practice phoner if you can schedule it before the actual interview - I highly recommend this as it was very helpful to get a feel for the questions that will be asked, the style in which they will be asked, and an actual person to talk to you about the responses that are expected. Both the practice and actual cases were pretty standard to what you can find in the online resources...not terribly difficult, a mix of 4 or so questions with 3 qualitative and 1 math (there may also be small math parts mixed into the qual sections, but nothing major). All the qualitative questions were pretty easy and answered at a high level...ways to reduce costs, increase revenue, target specific markets, risk mgmt, etc. Math question was pretty easy...if they ask you to estimate any numbers yourself (population sizes, total revenues, etc), try to make them easy round numbers to work with. Otherwise the math is high school level in difficulty, just be prepared to clearly walk your interviewer through your logic. The in person days are conducted once per month and are full days with a mix of case, behavioral and fit interviews with several consultants throughout. Obviously the big downside to this whole process is it's longevity...especially for those of us who are currently working full time, making time to fit in all of these rounds is not easy. One last point to make...call me crazy or sour grapes if you want, but I got the impression that it's much more difficult to land a McK gig without a top 20 MBA behind your name. Even with a well known and respected b-school MBA, I feel like I was expected to almost be overqualified if I expected to get a 2nd look without having a Wharton or Stanford alum status. I may be completely wrong, but my word to the wise would be to prepare two-fold if you're in the same boat.

I just finished the first step on the interview process which is the screening phone call. It was really casual and easy, more of a "fit" type of interview. Positive experience overall
