Crowd Gravity interview questions

After applying online, I got an email asking me to come to the office for an interview. I arrived and was invited to sit at a table with about 4 other people and an 'interviewer.' There were mini bottles of soda and cookies on the table and she passed out 4-5 pages of a quiz. One page was given each round. The questions included pop culture, geography, American History, etc. It was pretty awkward to say the least. As we left , we all joked in the elevator about how strange it was.
