CarMax interview questions

as soon I walked into the local dealership I was told to sit in a cubicle and do an online assessment, and the first thing they need is my social security number, I protested and was told by the sales manager either provide it or leave, he also stated that is the company policy and they have done it like that forever...you MUST provide you SS# FIRST to proceed...reluctantly I agreed and also basically signed my life away, then the usual computer screening. Next I had a sit down interview w/ the sales manager and I could tell that because I had protested the providing my SS# first thing--he had no real interest in me. He explained $12/hr while training, then after a month or so, you get minimum wage plus commission, no minimum wage if your commission exceeds the $7.25/hr for the hours you worked, then if they did pay you any minimum hourly wages those wages would be deducted from you next payroll w/ substantial commission to cover it. Hard to believe, but I received a rejection email two days later. My thinking was you are not required to provide your SS# until you are hired. I just interviewed a couple weeks ago.
