I applied through university. The process took 3 weeks. I interviewed at CarMax (Richmond, VA) in Mar 2010
Interview
First round consisted of one on campus interview with mostly fit questions and some behavioral. There is also one case question. The interviewer is just gauging to see whether you're interested in the company/job position and comfortable enough with numbers to make the next round. When you make it to final round, CarMax will give you a HBS case and several articles. You do NOT have to prepare a discussion about this case. This is just them selling themselves and a great way to show u did your research (definitely read the material). Final round is at CarMax's home office and consists of several interviews all of which are both behavioral fit and case as well (except for the last one which is used to wrap things up). During down time there will be some personality tests, drug test, and lunch with other analysts.
Interview questions [3]
Question 1
Word problem involving two equations to solve unknowns.
Basic behavior questions, walk me through your resume, why this company, why this role, why you are leaving your previous role. It's a video call. HR is punctual and friendly.

Interview
Had to take two assessments beforehand, met with recruiter, then a case interview with a member of the hiring team. Assessments were long and tedious, the interpretation/visualization one was difficult, math was timed and it's designed for you to not be able to finish. Recruiter was a basic interview/screen. Case (details included below) was rather difficult if you haven't done that type of math in years.

Interview
Went through two phone screens and then a case interview over the phone. The case interview went very well, and the interviewer immediately told me he wanted me to come in and interview onsite. I received an email from HR to schedule an onsite, replied with my times, and then never heard back, even after following up. Very poorly handled.

Question 1
Case was about where to place a bridge, basically just calculating expected value
