FIRST IMPERIAL TRADING interview questions

Was strange experience. I was called three times for them to reschedule the interview. I was offered a position on the spot & I accepted. I signed documents and given the normal w-2 forms etc to fill out & told to contact a manager for training for two days. Was finally contacted after three days of trying and scheduled training. The following day I am contacted and the offer is possibly being rescinded but I have not been explained why. During this 2nd meeting I was told because the paperwork wasn't returned the next day they hired someone else. That's not what I was told nor said during the interview. Was told they needed to wait for the background check at this point, yet the owner talked about things that I have not informed him of, so he must have done the check. I was accused of being an alcoholic, worried friends would come to the store, that the location was to far a commute. Basically the complete opposite of the way I was treated during the first interview.
