The process took 2 months. I interviewed at US Air Force (Eglin AFB, FL) in Jun 2010
Interview
Very professional staff made getting to interview easy; interview panel consisted of SES members for the Air Force material command and senior leadership; the interview itself was very scripted with other candidates asked the exact same questions with little time for any detailed discussion of job duties, working environment or expectations.
The process took 1 day. I interviewed at US Air Force in Mar 2008
Interview
Interviewed with senior chaplain, and the questions are all given in advance by the recruiter. Have to travel to see the officer, and then the interview is based on his/her perceptions. In my case, I had intel that the person wanted to know that I could work well with others in a pluralistic spiritual environment. I emphasized these qualities in the interview, and he was happy. Typical government experience in many ways.
