I applied through an employee referral. The process took 2 weeks. I interviewed at Johns Hopkins Applied Physics Laboratory (Laurel, MD) in Feb 2015
Interview
Pretty casual. Half day interview, met with 5 or 6 people who I would be working with. No exceptionally difficult technical questions, mainly focusing on things that I've done.
Interview questions [1]
Question 1
No particularly difficult questions, the typical tell me about your background, what have you done, what can you help our group accomplish. Pretty straightforward.
