Amazon SDE-1 interview questions

OA round was fairly easy if you have done decent amount of practice. There were two questions: 1. BFS/DFS on grid 2. Heap related problem After this in the assessment you need to explain the approach of both the questions separately. I was able to complete all the questions in time. Got shortlisted and waiting for interview call.

I got shortlisted after the initial coding round and was called for Technical Interview 1. There i was asked a question on graph (rotting oranges from Leetcode). The interviewer asked me to explain my approach and what i can do to improve the time complexity.
