Amazon SDE 1 interview questions

Passed Online Assessment (OA). Advanced to a 30-minute phone interview that included a live coding component. During the interview, I was asked about Depth-First Search (DFS) and solved a “Number of Islands” problem, which required applying graph traversal concepts to identify and count connected components in a 2D grid. I explained my reasoning, chose DFS as the traversal strategy, and worked through the implementation while discussing time and space complexity. This round tested both my problem-solving approach and my ability to communicate technical thinking clearly under time constraints.

I applied the job through LinkedIn, after 2 weeks got a mail for Online Assignment, the online assignment was around 2 hours long. In that there were 2 coding questions, 1 medium and 1 Hard. I was able to pass all the testcases for question 1 but for question 2 I went on a wrong track and not able to get the complete solution still manages to get 4 test cases out of 15
