I applied through an employee referral. The process took 2 weeks. I interviewed at Fidelity Investments (Boston, MA) in Jan 2009
Interview
Series of meetings with senior managers, peers and staff. It was a while ago but I think I met no more than 10 people.
In general, the interviewers do not have formal prep to conduct these - they wing it.
Interview questions [1]
Question 1
What makes you think you can get multiple groups to work together?
