J'ai postulé en ligne. Le processus a pris 1 jour. J'ai passé un entretien chez Two Sigma (New York, NY) en mars 2010
Entretien
Applied online, received invitation for HR phone interview about one month later.
Interviewer provided some background on the company and the areas for which I was interviewing, then asked a few basic questions about my reasons for seeking a new job, what I was looking to do, my salary history, etc.
Following the phone screen, the interviewer gave a two hour programming test consisting of two relatively straightforward problems to complete (the same problems other interviewees have posted in reviews).

It will be a phone interview first. They will ask you technical questions about probability/ statistics. The interviewer is friendly, but the question is not easy. The process is good.
