Amazon Software Development Engineer interview questions

round 1: Online Assessment which is 4 hours long but it realistically takes about 3 with 70 minutes for the two coding questions. It included two leetcode type questions, a work simulation test, and behavioral/work-style questions 2nd round: 3x60 interview. 3 hour long interviews back to back with the first round being both technical and behavioral, i.e the interviewer asking behavioral questions as well as coding and the 2nd round being only technical with the interviewer asking only coding questions. 3rd round was purely behavioral.

One online coding challenge, recruiter call, then onsite with 4 interviews: 3 coding and 1 system design. The recruiter was very flexible in finding an onsite date and the onsite experience was seamless. The coding challenge included behavioral questions and system design questions I was not expecting.
