I applied online. The process took 1 day. I interviewed at Cornerstone Research in Nov 2011
Interview
Only received one round of phone interviews. Did not know ahead of time that the interview would consist of two 45-minute economic case studies. Again, did not move on to the next round, but was told that there would be a second round of phone interviews (again, two, 45-minute case studies) and then a day-long interview with many potential coworkers and supervisors.

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.

First round 2 cases: Only cases questions.
Final round is onsite with 4 cases: They seem only care about cases, others are just fairly easy small talk. One securities, one valuation
I interviewed at Cornerstone Research (New York, NY)
Interview
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.
