Initial recruiter phone screen then hour long phone interview with two engineering leads. Two on-site visits each of 4-5 half hour sessions with 1-2 people from different areas; engineers, QA, project management, VP software. Some were conversational, some whiteboard coding problems and puzzles. Some specific C++ and multi-threading questions, others about figuring out algorithms. Also questions about previous work and responsibilities, how projects were tackled etc. All interviewers were pleasant, open to questions and I'd say I learned a few things from them too. Software departments are two blocks down the road from the main (and fancy) buildings and I got the impression that it would be a bit isolated from the main part of the company. Got the impression that the job would have a fairly narrow focus and there would be limited variety. Campus is accesible, but not convenient, from public transportation.
