OTIS Technical Sales interview questions

I met with the Otis Elevator representatives at my schools career fair. After having a great conversation with one of the head sales men, he asked me if I would like to have an interview the following day. The next day I had the interview and it was mainly asking about myself and why I wanted to get into sales. He told me more about the position, the company, and answered all the questions that I had. I thought the interview went really well, the interviewer seemed very interested but the following day I was notified that I had not moved on to the next round.

I am an engineering major who was recruited for a 'technical sales' position; however, there is nothing technical about it. They were just looking for salesmen,
