The interview was held onsite at the detachment's armory. The uniform was optional between ACU or ASU. I would suggest ASU if you have them prepared.
The board was a standard AGR interview board (President of the Board, 3 senior NCO reps, and a recorder). The proceedings were formal but the demeanor of the board members was relaxed adding to the ease of the interview. Total time interviewing did not exceed 20 minutes.
After board questions were presented, I was able to ask my own questions of the board members regarding future plans for the unit, details about how many personnel I would be managing, ect. It was a pretty good experience overall. Not nearly as stressful as other military boards you could go to.
