TSA (Transportation Security Administration) Transportation Security Officer interview questions

I recently just had an interview with TSA at BNA. The whole hiring process is probably the longest process in the world. I guess that has to do a lot with it being a government job and all. Well anyway, I went up there to get my interview done and it was me and 2 other women. They sat us down asked us for the information they needed and all that good stuff, then asked which person wanted to actually do the interview first. I volunteered. I go in and its a group interview in which a panel of people ask you theses simple scenerio questions and you answer them. I thought I did pretty good because I was calm and tried to answer the questions the best of my ability. When that was done they told me to hang outside while the deliberate. I waited about 3 minutes when the lady took me back in. I sat down and they said you failed your interview. At first i thought it was a joke bc of how simple the flipping questions were and stuff. I dont know i wasted like 2 months with this process and you look at all the old heads that have the job and you wonder why you dont.
