Amazon SDE-1 3rd Round – Hire or No Hire?
I recently had my 3rd round for an Amazon SDE-1 on-campus opportunity and wanted to get some opinions on how this sounds.
The round was ~65–70 mins. After a short introduction, I got one coding question: given a tree, cut one edge such that the difference between the sums of the two resulting trees is minimized.
I explained the brute force, then the optimized approach, coded it and did a dry run. During tracing, I had one mistake causing an infinite loop. The interviewer pointed it out, and after trying twice, I identified and fixed it myself on the third attempt. The rest of the solution, complexity, etc. was correct.
We then spent around 15–20 mins on behavioral/project questions, including a fairly deep dive into my internship and some AI-related questions. I couldn't remember one specific detail (database size), so I honestly told him I didn't know the exact number.
At the end, I asked a couple of questions and the interviewer answered them in detail. He didn't give any indication either way.
Also, there was only one coding question on the link, and when I asked if there was another, he said no.
For people familiar with Amazon interviews:
Does this sound like a Hire / No Hire / borderline round?
How much would the debugging mistake and not remembering one project detail matter?
This was my 3rd round, so I'm mainly trying to understand whether this sounds positive overall.
