After a phone interview and an engineering interview, where I wrote code in a Google Doc while speaking with the interviewer, I was invited in for a face-to-face meeting. I met with about twelve engineers and managers over eight hours, with a break for lunch. They asked very tough questions and really dug in to see how I think.

They gave me printouts of a couple of classes that worked together but were badly designed. The goal was to talk about how to better design the classes so they had clearer roles and better implementation.
