I applied through a recruiter. The process took 6 months. I interviewed at US Navy (Malden, MA) in May 2013
Interview
medical and background history. check if you are a good fit for the navy. you have to show up once a month while you wait. then you ship off and attend boot camp. it is not very hard.
It was no interview process. They check your background, credit, employment and education history. You go to MEPS, once approved you are sworn in and shipped off to bootcamp.
