I worked at US Air Force full-time (More than 10 years)
If you like teamwork this is the best place to be.
Everyone you work with will not share the same values.
I applied in-person. I interviewed at US Air Force (Vandenberg AFB, CA).
The interview process is actually a background and suitability investigation and can last up to two months. During the process you will be asked to fill out lots of paperwork and agents will speak with your coworkers, supervisors, and family member. The process ends with an interview with the local AFOSI Detachment Commander.
