Your interviewer is not only curious about how well you will fit into their work culture; they also want to know what kind of unique offerings you would bring. As they advertise on their website, "At CarMax, every associate is welcomed, supported, and valued for their unique perspectives and backgrounds." Your personality will play a part in whether the interviewer believes you would be a good fit for the CarMax team. Talk to the interviewer about your nature, what your coworkers have said about you, or what praise you've received in previous performance reviews. This is an opportunity to open up and let your personality shine.
