2 rounds of phone interviews, then 6 on-site. Standard tech interview questions: binary trees, string parsing. Lots of discussion of memory management, performance, managed vs unmanaged code. Whiteboard coding of course. I ended up in a conference room where the interviewers came to me... this means that there were no breaks in between, so it ended up being rather rapid-fire and I wasn't thinking as clearly by the end of the day. All the interviewers were really nice though and would have been good coworkers. Amazon seems like a fast-moving company with a lot of cool stuff happening. They're getting big but they haven't realized it yet... they need to grow up a bit and realize that working people to the bone is not sustainable nor does it produce good long-term results. They offer a lot of money but it's not so mind-blowing once you figure in healthcare costs, no annual bonus, etc. Lots of stock in the compensation, so your comp is strongly dependent on how you think the stock will do. At a P/E of > 100 (as of 12/11), there's not a lot of headroom there.

Interviewed for silicon team. Have only been asked about the domain specific knowledge in 1st round and system design in 2nd round and C coding in 3rd round. The interviews were 50 mins each.
