The process took 2 days. I interviewed at Susquehanna International Group (Philadelphia, PA) in Jun 2012
Interview
The phone interview was pretty relaxed, I was interviewing for about 6 positions. It was one person and I was asked some questions about myself, why I was interested in the company, and what I wanted to get out of my Co-op there. The people seemed really nice.
