Amazon Software Development Engineer(SDE) Intern interview questions

The interviewer was not very helpful during coding questions. He was kind of silent when I tried to explain the solution. The behavioral questions were kind of vague. The behavioral part takes about ten minutes and the rest is coding.

4 parts, 3 automated and 1 with an interviewer. Part 1 included Code Debugging then Part 2 was Technical Coding Questions which had 2 questions of medium difficulty, followed by Part 3 having SDE Simulation and lastly Part 4 which was Technical and Behavioural together for 1 hour.
