The process took 2 weeks. I interviewed at FactSet (New York, NY) in Mar 2011
Interview
First round of interview was over phone, a half an hour conversation with the group manager, then an on-site interview was promptly scheduled.
On-site interview consisted of an hour long written test, followed by four one-on-one interviews with team members, with a lunch in the middle.
Questions in the test varied from trivial (e.g., what's the difference between an array and a hash) to ones that clearly had no completely correct solution (e.g,, write a program that extracts all people's names from text). Each interviewer would then go over the test digging into one question or another.

Interview
It was a very casual interview. I was told the interview would start at 8:45 AM but it started around 10 AM. The interviewer was very friendly and walked me through my thought process towards solving the given problem. There were two rounds of interviews, purely technical though I did not get shortlisted for the second round.
