Austin Commercial Field/Office Engineer interview questions

I met the company at a career fair on campus and I was offered an interview the next day. The person who interviewed me was the HR rep. First the interview began 45 minutes late. Then, the interviewer told me that it wasn't so much an interview as much as describing what the company was about then answering questions I had, then him asking questions from looking at my resume. There weren't any basic questions that I was asked such as "where do you see yourself in 5 years" "tell me about making good decisions", the only question that was normal was one asking why I wanted to work at Austin commercial. I did have to do some quick math on the spot doing calculations of simple numbers, very easy though. Overall it was a strange interview, but not difficult.
