I applied in-person. The process took 6 months. I interviewed at US Air Force (Bloomington, IN) in Jun 2016
Interview
You simply find a recruiter who will evaluate whether or not you are a good fit for the Air Force. Some will not be there to help you, due to the fact that it is simply a position that took to possibly get away from their normal job within the military, and it's more stable hours and a work-life balance with their families, while others will care about what is best for you. There are multiple hoops to jump through but the biggest is meps, where you're evaluated through a test of your intelligence and health assessment. If you can get through meps, you'll have no problem getting into the military.

Talk to recruiter, enters you into the Delayed Entry Program(DEP), calls you when a job opens up. Simple. Passing score on test called ASVAB, I think it was around a 40 minimum, covered basic topics.

Question 1
No real questions aside from background screening. They cover what you've done in your past, weight, height, color blindness, depth perception, all kinds of questions; basically gauging how well of a fit you are for the military.
