5 people were conducting the interview. The interview was conducted in a Federal Building and consisted of 3 rounds of several people each. The questions were most on behavior although we got a few on technical stuff. The interview took place over a couple of days/rounds. Also they explained the benefits and the clearance process

interview was conducted by a panel and many of the questions often listed as typical were asked. I had prepared and practiced the questions so I was ready. The one question I did not answer well was about what books I had read... I have not read any books over the past year.
