The process took 1 day. I interviewed at Susquehanna International Group in Feb 2009
Interview
I had a brief 20 minute phone interview with SIG. They gave me notice half a week in advance to set up a time for the interview. My interview was on speaker phone with two people - one interviewer and one observer. The interviewer was straight forward and asked my to walk through my resume and talk about my poker-playing history. Also, I was asked a couple of basic probability questions before the interview ended.
