Amazon Software Development Engineer interview questions

There were 2 questions on Data Structures and Algorithms. First question was based on heap data structure and expected to implement heap by ourselves. Second question was on graphs. Interviewer was friendly throughout the interview. She will help if you are struck in a step or so.

I received a link to an online challenge and had 2 hours to solve the problems. There were 2 problems similar to leetcode. A few days after the interview I received an email that I was not selected.
