Interview Feedback
The overall process was smooth and the interviewers were friendly. I received the interview results on time within 5 days after the onsite. The recruiter also set up some time with me to discuss the feedback in detail. As per the feedback, I performed well on the LP part and cultural fitment seemed good to them. On the coding part, they found my code ease to read and modular but they expected me to ask more clarifying questions instead of jumping straight to the solution. On the system design part, they found me to be good on the requirement gathering part but suggested me to improve on how i communicate the details of the design that I have in mind.

I am planning to take the interview again next year. Hope this post helps folks planning to take the Amazon interview.
