What exactly does it mean in a DQ letter from DEA that you did not successfully complete the polygraph? I was nervous but have nothing to hide. Was even told by polygrapher that I had been coached. This was very untrue.
It means that you didn't pass. You've been branded as a liar. Worse still, the polygraph operator believed you employed countermeasures, and may have indicated such in his/her report. This could have a serious negative impact on your ability to find employment with other federal agencies.
