I applied through a staffing agency. The process took 5 days. I interviewed at The Cigna Group (Phoenix, AZ) in Mar 2012
Interview
I went through one screening interview from a staffing agency then an interview over the phone to test my technical knowledge then received the offer, very fast and efficient.
Interview questions [1]
Question 1
They were tech related, had to do with BGP protocols, and specifics about hardware, I imagine the questions change on the engineer who tests your knowledge.
