Alright guys, took the test.
The interviewer talked to me for about 30 minutes concerning his time in the military, since he saw I was in the AF. I suspect it was a 'softening up' thing, or maybe he simply wanted to chat. Probably looking to see if I was nervous or trying to hide anything.
The test itself was very short, only about 10 minutes. Cuff on left arm, chest expansion sensors on my chest (looked like baffles) and two clip on doodads for my fingers.
He told me to be perfectly still as any movement would show a false reading. Asked some baseline questions such as my name (a few times) then proceeded to the stealing/drugs part. A couple breaks to let my left arm get some feeling back from the cuff.
Test results..."probable lack of deception". I passed.
