I think I interviewed with the guy that posted a couple experiences up. Everyone in the group was really cool and I had a really fun experience. I've read before that it is good to talk to people to reduce your stress level. We had plenty of laughs throughout the day and it really mellowed me out for my interview. It was all guys in my group too. Very odd. Overall a positive experience. The interviewers were really nice, and obviously enthusiastic about meeting us.
