I applied online. The process took 2 weeks. I interviewed at FactSet (Norwalk, CT)
Interview
Simple phone screen. In-person interview. I met with 3 different groups of engineers that asked questions. Had to write answers on a whiteboard. They took me to lunch. The people are pretty friendly, but mostly fresh out of school with no other professional experience. I don't think they asked really valuable questions. I don't think someone knowing the difference between "private" and "protected" is a real indicator of their overall abilities.

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.
