I took a polygraph for the nsa a couple of weeks ago.  After doing (I think) 8 charts, the polygrapher asked me what I wanted to get off my chest about one question.  There was really nothing on that question, it was probably the question I was worried least about.  So I said I couldn't imagine what it could be, and he asked me again, explaining in detail what the question didn't mean, and said that I was probably worried about something there.  But I wasn't, and there wasn't anything I could think of and I said so.  Then he said OK, and I left.

What do people think of this?  Was he just fishing?  I didn't get defensive at all, stayed very calm, which was easy since I was not at all concerned about that question, so does it sound like I'll have to take the poly again?  I of course would rather not, but if I have to, I will.  I was told by others that if I didn't hear in a couple of weeks, I was probably all right.  But is it possible for me to be DQed on the first go?  Would I hear about that?

FWIW, the poly itself was R/I exactly as described on here and I didn't use CMs.  But there was barely any post-test interrogation (not as some have described, just the questions above.  I doubt it took 5 minutes, and it wasn't very intimidating), and the other people I talked to after had similar experiences.

The quizzing you received about what you "wanted to get off your chest" was indeed part of a fishing expedition -- that's the whole point behind polygraph screening. Unless you made a disqualifyting admission during the pre-test phase, I doubt you'll be disqualified at this point based on the account you provided here. But don't be surprised if you're called back in for one or more follow-up polygraph interrogations: multiple sessions seems to be the rule and not the exception at the NSA.
