I applied through a recruiter. The process took 4 months. I interviewed at US Air Force (Colorado Springs, CO)
Interview
My interview was 20 years ago so I don't recall the specifics. There were actually a number of interviews with the Recruiter, and more interviews on the day that I took the Enlisted oath. For the most part, I was asked about criminal history, drug use, personal and professional goals, and previous work experience.
