I applied through a recruiter. The process took 5 months. I interviewed at US Air Force
Interview
Recruiters find you or you find them. MEPS initially screens you health and test scores, Basic Training Screens your ability to learn under pressure considering that you learn it there. Tech school tests you just as any trade school would. My advice, just jump through those hoops without failing and your in.
Had to do a test and go through a board. All those going for E5 must take a test based on CSCS and air force history. Then you area ked based on score and will promote if you are above cut off.
I applied in-person. The process took 4 weeks. I interviewed at US Air Force (Florence, KY) in Jan 2017
Interview
You talk to a recruiter and they talk with you to assess your temperment, qualifications, and basic personal history. They will schedule you for the ASVAB test which determines what jobs you qualify for. Then what jobs you can select depends on the govt's needs and how long you are willing to wait to get the job you want.
