Amazon Graduate Engineer interview questions

I was sent an Online Assessment email in the day of application. They had a list of helpful links on how to prepare for the assignment, including a full demo of the process and the coding environment which behaved exactly like the real HackerRank environment. The OA had 2 LeetCode style questions, both had a very long description and took some time to process. Besides that, the questions themselves were quite difficult, the first one was easier than the second one but it was also difficult. Didn't do good enough so I was rejected a few hours after completing the OA.

I have one question regarding arrays and binary search. Overall, it was a very positive experience — I truly appreciated the interviewer’s supportive approach and the clear guidance provided throughout the discussion.
