I went thru the TS/SCI w/FSP for a 3 letter top tier agency and it was a joke. They interviewed my mom, sister, old coworkers/bosses and old teachers. Then just asked me normal questions. They asked my mom and boses normal questions too. It's nothing like in the movies/TV shows and plenty of bad apples get thru lol.

The former head of the DCSA and FBI NYC field office both got caught doing bad stuff. The process is broken and honestly isn't that good . It gets people who aren't committed out, but also makes tons of good candidates go with other jobs, because it takes at least 4 months to do. Mine was 9 months long + 3 months to get an offer initially.
