I applied through a recruiter. The process took 2 months. I interviewed at US Air Force (Flint, MI) in Jan 2009
Interview
In comparison to the civilian sector the interview process is somewhat nonexistent. The biggest factor that comes into play is making sure you don't disqualify yourself with a previous medical issue, financial status, drug use, etc. the recruiter is the only obstacle to overcome in the initial interview process. If you trip him/her as an actual hiring manager the process will run smoothly.
Interview questions [1]
Question 1
Why do you want to join the worlds greatest Air Force?
