Yes, in fact, I did. I only actually met a couple of people, but I noticed a lot of smiling faces.

Funny story: They have two floors of a multi-story building. I got off the elevator on the wrong floor on my way from the recruiter (in the same building) to the interview, and an employee very quickly noticed my confused expression, and helped me out. It was embarrassing, but a lot less embarrassing than it would have been had I spent 15 minutes wandering around aimlessly.
