Sentry Security interview questions

I was contacted by Sentry and offered to interview for a short term contract in Arlington (a job I did not apply for). I was between contracts and agreed to interview because it qas a three month comittment qith flexible hours and shifts. The gig was hospital security related so I went out of pocket and completed a HIPPA course prior to the interview as well. I drove out to Fairfax to interview and encountered the most disorganized and unprofessional personnel I've ever dealt with. Suffice to say the interviewing official told me not to waste his time and that he'll show me the door after finding out why I requested mid day shift (anticipating a call for a polygraph for a job I was waiting on that would take a few months to start).
