I was greeted with a lock door and struggled to get anyone to answer the phone so the door could be unlocked. I tried knocking on the door. I was give a list of questions to study for a few minutes and then I started to answer. It seems like the questions were very straight forward but rating the answers could be very subjective.

Sent me a list of interview questions in the interview and had me answer them in any order (8 total). There was also time for some questions at the end. Took about 1 hour.
