Amazon

First, they sent an OA from HackerRank with 70 time limits. Then, there was a phone interview for a background check. Finally, the in-person interview consisted of one graph problem and one DP problem that I had no idea how to start.

I applied through an employee referral. I had to solve a graph problem using topological sort. They asked me to solve this problem where the constraints were course names with prerequisites, and you have to return the order in which all courses need

It was great! The interviewer was on time for the interview. He gave me enough hints to solve the question. I was asked two behavioral questions and one technical question. Then, I asked him about his experience at Amazon.
