For the Air Force, the interview process is different from the normal interview of a company. They will ask personal questions to verify your eligibility for enlistment. The most personal questions will be through MEPS, after the initial interview. You will also have to complete the ASVAB to figure out what jobs you qualify for. Your recruiter will help you with this. They are here for you, and if they can find a way to enlist you, they will.
