The process took 1 day. I interviewed at CarMax (Richmond, VA) in Oct 2010
Interview
I applied via college recruiting website. The interview was 1-on-1 with a Senior Analyst. The interview consisted of mainly behavioral questions. Be prepared to tell them why you want to work for CarMax. At the end there is a short "story problem" where you have to do some basic math. This part was fairly easy.
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.
I applied through university. I interviewed at CarMax in Jan 2019
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
The process took 2 weeks. I interviewed at CarMax (Richmond, VA) in Mar 2020
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.
