CarMax interview questions

Applied online got a call a week later and had a short phone interview. They said they really enjoyed speaking with me over the phone and that they would have a manger call me to schedule a face to face interview. I got a call from the manager a couple hours later to come in for a face to face. My interview was at 1:30 and then they call me around 11 saying that they needed to push it back to 3. So I get there at 3 and wait awhile for someone to see me, they set me up on a computer asking questions basically if im a drug addict or criminal. After that i wait awhile longer waiting for someone to see me. I finally get to a manager to interview me, he asks me 4 questions off of a piece of paper and doesnt look at me during the interview at all and gives me the "you should hear something by next week" phrase and basically rushes me out the door and doesnt even walk me out. At the point i knew I didnt get the job but if they had called me i would of said "thanks, no thanks" I would never work for a company that handles interviews that matter. They likely hired someone earlier that they interviewed and even made me go through the trouble of rescheduling my interview.
