I applied through an employee referral. The process took 1 week. I interviewed at Lisner Auditorium (Washington, DC) in Jan 2007
Interview
it was simple; i went to the connected university and had a close friend that worked there. she referred me, there was a short application and interview portion, and she sent me out to get a W2. This was back in 07, however, so the economy was a bit different than 09. It is likely harder to get such a position now.
