I applied online. The process took 2 months. I interviewed at Oliver Wyman (Dubai) in Oct 2014
Interview
I applied online and did the numerical test, then it took several weeks to schedule a first phone interview (with a manager) and after that 3 weeks for the second phone interview (with a principal). The process ended there for me but I think there are 3 interviews with consultants in total and one with the HR. I have never seen a process that long and burdensome. Casual consulting interview, fit questions, market sizing and small business case.
Interview questions [1]
Question 1
It is christmas eve, you are a manager of a toy store and your cash register system is broke. What do you do?
First behavioral interview super annoying that it is 3 at once. Typical tell me about yourself and why oliver wyman. The interviewer seemed like already made up the decision and it was very uncomfortable to undergo the interview.
Did not recieve a callback.
There was an online assessment which tested mostly mental math and reading graphs. Then, there was a 30 minute case interview and a 30 minute behavioral. Fairly straightforward and standard, with the case being easier than average.
