Postal personality assessment test

Does anyone here have experience with the personality assessment given by the USPS one takes before the exam? I recently took it and answered honestly but received an email saying that I am ineligible for the positions. I am confused because I have spotless record, I have worked for years with postal contractors and work in terrible weather, which I feel would make me an ideal candidate for a carrier position. I took the practice tests and was acing them but I apparently I failed the personality test. I call BS but what can I do, might try again in a few months.

Thought this was a test to see if you'd go postal and kill Phone Post 3.0

My cousin works for the USPS psychiatric board, he says the only personality type that fails that exam, are latent homosexuals with a high risk of acting on their sexual predator instincts.
