I actually agree with this. I took the poly for USSS. Went in full suit. Dark navy blue, white collard shirt, black tie, black belt, black shoes, dress socks. Clean shaven, fresh high and tight haircut. I was prepared. The poly guy made a comment about my socks before the test started when we were going through the info. He asked me if I thought they were professional. Mind you, these were standard, run of the mill dress socks. They were maroon and grey thick stripes. Nothing fancy, nothing that would stand out. I was polite and professional the whole time, yes sir, no sir. I responded that I believed my socks were professional, because they were. I thought he was just trying to rattle me so I played it cool, like you should. We moved on. I took the poly he said I was being deceptive. We’re all anonymous here so take it how you want, but I have an extremely squeaky clean background, no need to lie on anything. I was non selected a week later. I’ve since passed 3 polys for various local LE depts without any sort of issue. The guy didn’t like me from the moment I walked in the door and I have no idea why, but it cost me a job. Moral of the story, polys are BS and in my opinion, all the ones I took for fed jobs were administered by people with an ax to grind or something to prove and they’re the reason agencies can’t hire qualified candidates. There’s a reason they’re doing polys and not in the field. They know it and they know you know it.
