Interview rounds were on Problem solving, Algorithms, Data structures, Coding There was no phone screen/written test. First 2 rounds were at similar level (later got to know that SDE-1s took these interviews), Candidate was called for further rounds, if at least 1 round was "Meets Amazon standards" and another "Not sure". If any of these interviews went bad, candidates were eliminated immediately. These interviews were 1 hour each, mainly focusing on data structures and coding. Third was Hiring Manager round, where in both technical and HR questions are asked. This round spanned for 1.5 hours, Varied questions were asked. Approach is checked, and time was given for difficult questions, Fourth was Culture Fit round (1 hour), Interviewer was late and apologized twice for the same. This round was to check if one is right fit for the role at amazon. This round surprisingly had a data structure question. Then, on current project, challenging situation, why should we hire, etc. Fifth was another technical round, This time with senior interviewer (SDE-2 or SDE-3), again for Problem solving, Algorithms, Data structures and Coding. There was a puzzle to solve at the end. Feed backs after interview rounds were prompt and regular. I was informed that I was selected the next day after last round. The offer letter was dispatched in another 4 days. All Interviews took place at Amazon office in WTC building, Except first round, where interviewer started off with questions straight away, all other interviewers were friendly. In general, I felt interviewers very smart and also work environment seemed good.
