The process took 1 day. I interviewed at Cornerstone Research (Boston, MA) in Sep 2011
Interview
Two back-to-back interviews. First 15 minutes spent on fit questions, they're really interested in getting to know anything research-related your resume. Next 20-25 minutes on a case and they give you a couple minutes at the end for your questions about the firm. The guys I spoke with were really nice and smart. Too bad these were my first case interviews and I didn't really prepare well.
I interviewed at Cornerstone Research (San Francisco, CA)
Interview
First round is 2 back to back interview rounds with two different Cornerstone analysts/associates in the office you indicated. Pretty standard Econ consulting cases, not too difficult. Cases are adapted from Also some basic behavioral questions about yourself, interest in the field, research experience, etc.

Everyone was welcoming and the cases were interesting. The interviewers seem to be interested in seeing how you think as opposed to looking for a particular answer like you might find in a management consulting interview or a finance interview.
