Amazon Software Engineer interview questions

2 rounds of phone screens (mostly technical questions). Then onsite with 5 45-minute sessions. Each session is one on one (or with shadow), mostly doing whiteboard coding. One of them should be "bar-raiser" interview, but I can hardly tell which one it is. Lunch discussion does not talk about technical stuff, but can still be a hiring manager interview (mostly behavioral questions). Recruiter coordinated everything, can be slow and I had to probe them for status update.

The first round was an online test where they asked basic programming questions. The second round was a phone screen where they asked one technical question, and multiple behavioral questions. They generally do not seem to ask recursion based questions. They also seem to prefer linked list questions
