I applied for several positions at Amazon Worldwide. From there my resume got selected for SDE 1 at Amazon Karnataka and SDE 2 Ireland. They sent me assessment link on hackerrank to complete within a week. The online assessment round had 2 parts - 1. 2 Coding questions and respective solution approach and complexity for 105 minutes. 2. Work time flow questions - mostly work related behavioural questions for 15 minutes. I completed first coding question and passed all test cases. Also I nicely wrote solution approach and complexity analysis. Second coding question, I passed 12 out 17 test cases and wrote solution approach and complexity in simple way. Because I had less time at the end so I couldn’t enhance second question to pass all test case. Right after an hour, I got mail that they will not move me forward for this role. Hence I was rejected. I thought passing one question completely and another more than 50% should be accepted to move to next round but I don’t know if they want a candidate to solve all questions and pass all test cases for all questions. The above explanation is both for Karnataka and Ireland location online assessment in Amazon.
