I applied through a recruiter. The process took 1 day. I interviewed at FactSet (Norwalk, CT) in Oct 2011
Interview
I got pulled aside by a recruiter was everyone was walking by him. He like my resume and they said they'd give me a phone interview. The phone interview was really easy. Write a loop that prints out some numbers, then program a singly linked list. I passed this part and they flew me out to Norwalk, CT for a day long interview.
This interview started early and it kicked off with a get to know the company. After that, it was several one-on-one sessions. First was a code review session, where I was offered code in C++ or Java, and I had to discuss the bugs. Next were two technical interviews where I had to "code" stuff in C++, data structures and the like. After were some HR interviews, which were more like Q&A about the company.
