After sending in my resume and cover letter, CarMax Strategy Group got back with me and set up an initial phone interview. As the initial phone conversation, and with no insight as to what this phone call would include, I was extremely surprised when the interviewer began a full case with me. To say that I was not expecting a full case would be an understatement. The interview was behavioral and an overview of your resume and activities to start, as one would expect from an initial phone interview. However, the surprise from the math intensive case interview was too much for me to overcome.
