I applied through a recruiter. The process took 1 day. I interviewed at US Navy (Oklahoma City, OK) in Jan 2011
Interview
Easy interview. Just take the test.. pick what you are qualified for, pass the physical and join. No big deal. There isn't a lot more to say here. You pretty much take the test and you're in. It's not a typical job, so it's done differently, obviously.
Interview questions [1]
Question 1
A ton on the test, but they're all general knowledge nothing to stress over.
