The interviewer is trying to assess if you might be considering a career with CarMax rather than just a temporary position until something better comes along. Reassess your career goals and determine how your career goals are aligned with a career at CarMax. Examine the keywords they incorporate into their value propositions, and if able, naturally weave them into your vocabulary. For example, here is a value proposition from their website: "On the road to success! Put your career in gear and make an impact on the industry. Receive ongoing training and development in a climate-controlled environment. We're committed to helping you innovate, learn, grow, and shape your career in ways you haven't even imagined." This will reassure your interviewer that you are eager to demonstrate your abilities and cross-train in other areas.
