CarMax Accounting interview questions

I was referred by a current employee. I applied then receive a call a week later. I interview with five different mangers. 30 minutes total time for each interview. The first interview was over the phone. Then I was invited to do a in-person interview. The first set of mangers was easy going. They loved me and wanted me to interview with their Senior managers. Then another manager call to do a phone screening. Very long drag out process.
