I applied through college or university. The process took 1 day. I interviewed at BNP Paribas (New York, NY) in Jan 2010
Interview
I applied through on-campus recruiting and just completed the first round of interviews. The interviewer is very nice and friendly. Basically, he just asked me a project I did before. He went into technical details involved in the project. Additionally, he asked open questions to test your general understanding about derivatives.
