Amazon Software Development Engineer interview questions

The interview process was surprisingly cursory and felt a bit shallow, although very low stress. There was an online test that involved seven coding problems and then a phone/screen-sharing interview that lasted 45 minutes and involved one longer coding problem and two shorter spoken answers. I was expecting a much more extensive and more difficult process than the interview process I participated in.

Had two phone interview. Each one has Computer Science fundamental questions (basic Java and questions on locks etc.) and a coding question (Traversing a binary tree). After that was an onsite interview. Met about four interviewers. Coding questions mostly on trees, stacks, queues, etc. There were also general questions like how would you diagnose if someone reports that your website is slow. What would you need to change to launch a website like Amazon in a different country (e.g. Korea)?
