I interviewed at Cornerstone Research (Menlo Park, CA)
Interview
The interview was split between behavioral (20 mins) and a economic case. This is the first round, once you do this you will have more case rounds. The superday is 4 back to back cases (40 mins each) in person.

The interview process was succinct, but it was difficult. Depending on the office, they take only a few candidates, so it is extremely competitive, so bring your A-game; you will need to be near-perfect.

Interview
Round 1 consisted of two interviewers. Each one asked a few behavioral questions, followed by a short case. Both interviewers were definitely conversational and easy-going. Each interview is around 30 minutes long.
