Amazon SDE 2 | BLR | Interview Experience

Hi Everyone,

Giving back to the community as you guys have helped a lot.

Onsite BLR office F2F :

Round 1 (System Design - F2F):

This was taken by the HM. Was a very chill guy and I felt he was genuinely listening to my answers. First half was LP's and AI related questions like how do you use AI in your day-to-day work.
The HLD question I was asked was Personalized Auto suggestion. A little mix of Top-k was also asked for trending suggestions. And also Multi-language support.
Luckily was able to answer all the question related to scalability, latency etc.

Feedback from HR: Strong Hire


Round 2 (DSA - F2F):

Different wordings but it was Meeting Rooms III : https://leetcode.com/problems/meeting-rooms-iii/description/

Lowest Common Ancestor of a Binary Tree II : https://leetcode.com/problems/lowest-common-ancestor-of-a-binary-tree-ii/description/

Solved both. And then LP questions.
Funny thing was for one of the question I quickly gave the optimized solution directly and so he was more interested on looking for a brute force solution.

Feedback from HR: Hire

Round 3 (DSA - F2F):

Swim in Rising Water : https://leetcode.com/problems/problems/swim-in-rising-water/description/

Matrix + Dijkstra's algorithm

Solved both. Had to dry-run them. And then LP questions.

Feedback from HR: Hire

Round 4 (Bar Raiser - Virtual):
This round was only for LP's. I honestly feel that these bar raiser rounds are mostly dependent on the interviewer. I have given few mock rounds with different ppl at Amazon and I always did well with them. This is where it went downhill for me. For some reason he was just not happy with my answers to the LP questions he had.

Feedback from HR: No-Hire

Final Verdict : No-Hire. The HR told that only if my LP's were a bit better my verdict would have been a Hire.
As how everyone says DON’T IGNORE LPs.
Well I couldn't make it but I really hope you guys do.
