I applied through a recruiter. The process took 4 weeks. I interviewed at Citco (Charlotte, NC) in Feb 2011
Interview
They were staffing the office from scratch and the interview process was very informal. I think as long as you had decent experience on your resume and presented yourself well in the interview, you were offered the job.

Question 1
None were challenging at the time. It may be different now.
