I applied through college or university. The process took 3 weeks. I interviewed at FactSet (Chicago, IL) in Oct 2011
Interview
Met staff during a college career fair. We talked about me, who FactSet was (I had never heard of them), and we talked about how it might play to my interests. I gave them my resume after talking.
Several days later I received an email asking for me to set up a phone interview, which followed a couple days later. The interview was a few simple questions, procedural programming stuff, with no OOP or anything. I got an email later that day to set up an on site interview.
The next week I went in for an interview that lasted approx. 7 hours. It consisted of 5(6?) 2:1 interviews about things like debugging, OOP, design philosophy, etc. Talked about my resume with every group, and got to know each of them. On of the groups took me out to (a nice) lunch and we talked about my interests outside of work. The final interview was with the lead boss, which was about 1/2 an hour, and I was given some tougher problems to solve conceptually.
3 days later, I got an offer.

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.
