Informal mixer, then had an in person interview where they asked questions, gave me a tour, had me write a short "writing sample" (answer two questions and send by email while in the office), and let me listen in on a few calls. The overall feeling I had was that it was a little disorganized. I interviewed with two people, then did the writing sample, was left there for a while even after I finished, then listened in on another person's calls, then was led out rather abruptly by a totally new person. It was a little weird.
