I applied in-person. The process took 3 weeks. I interviewed at FactSet (Norwalk, CT) in Mar 2013
Interview
Initially met at a career fair. Sat down the next day for a light technical interview involving some basic question on object oriented design and a very simple programming question.
I got an e-mail about 1-2 weeks afterwards with an invitation to do an in person interview. They flew me out to NYC and got me a driving service from NYC to Norwalk. The next day, I had several interviews.
A demo, a code review, an OO game design interview, an algorithmic design interview, and a couple non-technical interviews.

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.
