I applied through a recruiter. The process took 2 months. I interviewed at Lockheed Martin (Washington, DC) in Apr 2015
Interview
Process was simple. After reviewing my resume, supervisor and I had a 10 minute phone conversation, it was immediately apparent that I was well qualified, so supervisor requested writing samples and set up an interview with the government client. That went well and I started fairly quickly (already had a security clearance which sped it up).
