The process took 2 weeks. I interviewed at FactSet in Jul 2010
Interview
I was first contacted by email and asked to provide a short piece of sample code before they could set up a technical phone interview. You can expect to discuss the code you had provided along with design choices and possible ways to improve it.
After the phone interview, I was scheduled for an on site interview consisting of an office tour by HR, a product demo by a software engineer, three technical 2:1 interviews, lunch, and an interview with a software director. The first two technical interviews covered OOP and algorithms while in the last I was asked to debug code in c, c++, or java. They give their final hiring decision within 24 hours
