I applied in-person. The process took 5 days. I interviewed at ATEC (Alexandria, VA) in Feb 2012
Interview
Had a panel interview with a dozen individuals. They took turns asking me various questions. They showed me a presentation of the process the company uses when running programs. They asked about military background, and they asked a lot of forecasting questions
