The process took 3 days. I interviewed at Cornerstone Research in Nov 2010
Interview
The interview process consisted of two phone interviews which each consisted of two separate interviews, and then a day at the office with 5 separate interviews. Each interview was a few questions about background and resume. and then a case. They tend to ask why you are interested in economic consulting and about recent work experiences. Everyone was friendly, and helpful.
