I wouldn't believe anything anyone says to you.  You don't know what the outcome will turn out to be until after you receive word on whether you passed or failed.  In my case, and from reviewing my copy of the investigative BI that I received, I was rejected because of inconsistent entries on m SF-86.  In my case, I made some rather obvious mistakes in documenting my previous employment circumstances, which had I clarified it with my AC beforehand, might have resulted in a better outcome.  From what I can ascertain from reviewing a copy of my BI, I did not fail the polygraph because a notation is entered "NDI" so apparently the rejection of my application was because of the omissions on my SF-86.  Because of this I was viewed as being deceptive.  I don't understand it, because I really did not intend to deceive anyone, the mistakes I made on the omissions for the SF-86 were from my not understanding exactly what I should disclose.  I submitted my SF-86 without checking it over with my AC.  My whole point is that it looks like I passed the polygraph but was still looked at as being deceptive because of the omissions, which were considered to be deceptive and misleading.  I think it just shows then, the polygraph is not an accurate way to determine whether someone is lying.  I will say this.  When I took the polygraph, I honestly did not feel I was being deceptive in any way at all.  In fact, only after I received a copy of my BI did I realize the seriousness and gravity of the my initial mistakes in completing the SF-86.  It is ironic, however, in that after reviewing a copy of my BI, I noticed things that were not true and am confused as to how something that wasn't accurate or true became part of the final summary on me.  I am unsure if there is an appeal process, but don't think so because I believe if there were, I would have been notified of it by the FBI.  It bothers me that I apply for a position with the FBI, and after submitting my application, I am rejected because of the way I completed my SF-86.  So now, not only do I have a rejection from the FBI, but I have an investigative file on me that is not 100 percent accurate filled with a number of derogatory assessments of my character.  Had I not applied for this position in the first place, I would not have to worry about this permanent derogatory FBI record that will always follow me.
