Le processus a pris 1 jour. J'ai passé un entretien chez Cornerstone Research (Boston, MA) en févr. 2012
Entretien
They asked some behavioral questions mostly about my past internship and projects.
Then, they performed an intellectual property case study by sending graphs via email before phone interview.
But the recruiter was friendly

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.

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.
