Amazon Senior Software Developer interview questions

Talked to five people at their downtown Seattle office. Starting at 9 a.m. the first three were engineers who each asked algorithm questions to be coded (not outlined, coded) on a whiteboard in about 45 minutes each. The problems would be moderately challenging to do at a computer and I found them to be difficult to do while being watched, while taking about the code, and while writing on a whiteboard. The next two were with personality interviews with management - lunch with the hiring manager and then 40 minutes with the manager's manager. There were no software design questions, only basic algorithm stuff, which was a surprise given that the position was for a senior software engineer.
