Nielsen Field Representative interview questions

I interviewed for the position in Greensboro, NC. The previous interview was still going on when I arrived and was a few minutes over my scheduled time. The person interviewing me did not apologize and he acted like he didn't want to be there. I did not get a good vibe from my interviewer. Maybe it had something to do with me being the last interview of the day on a Friday. I've never had a bad interview, but that day I left feeling like it was a waste of my time.
