Amazon Software Development Engineer interview questions

Interview process went very smoothly, there were 4 interviews, 2 datastructure and algorithm and 2 design, I enjoyed all of them, and interviewers were very nice and provide useful hints.

Interview was tough but well structured. You meet four different people and each person asks you a different question. Data structures, algorithm, object oriented design and system design. There are also behavioural questions at the start that focus on the leadership principles.
