CarMax interview questions

I interviewed in Irving and did not get a offer. I'm not sure what happened, I rocked the first interview and then when I met with the Production Manager he didn't seem to care to be there. He had already postponed the interview due to snow in Dallas a week and forgot to call me so I go all the way out there in the ice and the store is closed and he didn't bother to call. I also had a weird moment at the end of the 2nd interview with him that was like step outside while we discuss and then he came out and said he would get back to me in a week. Well overall unprofessional opinion of Carmax upper management. I would like to get some feedback other then a generic letter.
