Process began with an online assessment involving basic math and business skills. After a week, had a phone interview with a current Senior Analyst. As noted, this was difficult since there was a case component that was not announced in advance. The case itself was not hard for anyone with previous casing experience though. Two days later was called back and invited to an on site interview, travel expenses covered. This was a gauntlet. It began the night before the actual Super Day, with a dinner with current analysts. Then the day of, several behavioral and case interviews, as well as a drug test. Nothing was too difficult or unexpected, although the cases required a decent level of familiarity with statistics. All the staff I interviewed with were quite friendly, and very curious about my personality and interests. It is evident Carmax heavily emphasizes fit among their analyst classes. Within the next three days, I was contacted by HR who let me know I received an offer. Over all, not the most difficult interview process, but certainly a thorough one.
