CarMax interview questions

I was interviewed by three different managers. They asked me questions about previous job experience, how i handled situations, am I more outgoing or internal.

Applied for a position after being referred to CarMax, within 2 days I was contacted by CarMax to come in for an interview. Immediately, I sensed that everyone at the store was happy to be a CarMax employee. I met with the HR person who led me to a computer where I verified that the information I had typed on the online application was correct. Additionally, I filled out more e-forms on background checks, release forms, etc. (typical HR stuff). Afterwards, I was told to wait in the sitting area to meet with a person from the purchasing department (I repeated this "wait in sitting area to meet so-and-so" 5 times--most annoying part of the interview). The first person came and enthusiastically introduced himself, asked how my day was, etc. while walking me to a room near where the computers were (leaving me to ask why I wasn't asked to wait in this room to begin with). They asked questions about my ALL of my previous employers what I did, how long I was there, why I left, why I didn't include them on my resume (as if I thought I had to include a job I worked at when I was 15 years old). Afterwards, I went back to the sitting room and waiting for the next person. This time 2 people came and introduced themselves, they asked typical interview questions from a sheet of paper. Back to the sitting room, waited for the next 2 people. Asked more interview questions from a sheet of paper. Back to the sitting room, waited for 1 more person. Finished. 2 days later I was called with a job offer. After accepting, I came in a few days later for a urine sample and started roughly 2 weeks after that.
