I applied through an employee referral. The process took 1 week. I interviewed at WebAssign (Raleigh, NC) in Mar 2012
Interview
Fairly quick and laid back. It was much less hassle than some other companies I've interviewed with. I don't think they did as good a job as they could have describing the position, because it is fairly unique and needs to be spelled out clearly.

Question 1
I don't really remember the specific questions they asked, this was a few years ago. The question weren't difficult, though. Fairly standard stuff.
