I'd worked a limited number of times filling in as needed at the store I was interviewing at. Therefore, I was familiar with the interviewer and the duties involved for the job. I came to the job interview prepared with actual examples of difficult customer instance and how I handled it. Success story. Story of how, when, & why I got started and stayed in this great field. I was asked to give specific examples of how I'd "drive sales?" I waited approx. 10 days after interview for offer of the promotion and I accepted.
