The in person interview was very short, definitely under 30min, however, before the interview I had a phone screen interview that was approximately 20min. My interviewer was very professional, polite, and lovely to talk with. I had the same interviewer for both the in person and phone screen interviews. The experience was very positive overall. Much of the interview was a tour of the office, which gave me the impression that I had a very good chance of getting the position, which I did indeed get.
