I applied online. The process took 4 months. I interviewed at ATCC (Manassas, VA) in May 2015
Interview
Standard process. Primary phone interview. Secondary in person interview. They ended up taking awhile to process my application, which was ok with me because I needed to finish up a project at my previous job anyway.
Interview questions [1]
Question 1
They asked me about specific systems they were implementing, and whether I had any experience with them.
