I applied online. I interviewed at CarMax in Mar 2019
Interview
Applied online through CarMax website. And after several days, followed an online assessment which is some math problems. Then the HR called me to verify identity and asked questions like when will you graduate.
I received an email to complete an on line assessment 8 days after applying. The assessment is timed with practice questions before. You have 25 minutes to complete the assessment. You can practice as many times as you would like.
I applied through college or university. The process took 3 weeks. I interviewed at CarMax (Richmond, VA) in Jan 2016
Interview
It was a phone call interview asking basic questions on background, resume, and interests short term and long term. It was a classic first round interview that just wanted to check behavioral basically.
