I applied through a recruiter. The process took 1 week. I interviewed at FactSet in Oct 2009
Interview
Had a brief phone interview about my background and my skills, but nothing technical.
Went in later that week for an all day interview. Questions were more about algorithms than specific C++ syntax. It wasn't that difficult, but my nervousness and unpreparedness cost me dearly.
I wasn't really asked about my specific reasons for wanting the job nor was I asked what I thought of FactSet.
