Tough long and strenuous. Multiples tests with medical exam.
School is 3 months long.
Long process with multiple ways to get in the door. You will learn so much and use it practically every day
I applied in-person. The process took 6 months. I interviewed at US Navy (North Charleston, SC) in Sep 2015
Interview
There was no interview all you do is fill out a bunch of paperwork and see if you qualify. Pretty much anyone can work there. Doubt there is an easier job to get than this.
I applied through a recruiter. The process took 1 week. I interviewed at US Navy (Asheville, NC) in Nov 2014
Interview
If you pass the test you will be given a background check. The test is pretty hard so study and be ready to sit for a hour or so. There will be other candidates present as well. Overall the interview preocess is easy.
