Somewhat unprofessional, I felt like the person interviewing me really didn't want to be talking to me and they were just doing it because they had to. Also they told me absolutely nothing about the job. They just wanted to know about me and why I thought I was qualified to work there.

Very simple. The manager asks a variety of simple questions based on the role you applied for. Not intimidating at all- very laid back company and environment. Did not ask anything specific. Did have to do some tests before the interview- had a phone introduction and then a face to face interview.
