I applied in-person. The process took 4 weeks. I interviewed at CarMax (Atlanta, GA) in Feb 2015
Interview
Submitted resume and about 2 weeks later got a call to schedule an interview. Interview had a brief get to know you period then a really simple case study (there was a correct answer... you will have to do math) and more information about the position. Should hear back in the next few days and if accepted the next step will be a tour of the site culminating with an offer.
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.
Interview questions [1]
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.
