The interview was fairly informal, as I had previously done business with the interviewer. That said, everything was very professional. The interview lasted about 30-45 minutes and the interviewer had me fill out an application to forward on to their HQ at the end of our meeting. I was disappointed that I did not get an offer, though I knew I wasn't a perfect fit for the position. I was more disappointed that the interviewer did not at least send me a note about the lack of offer, as we have a mutual friend who assisted in setting up the interview.
