- 29 Mar 2026
Summary
I interviewed for a Senior Software Engineer role at LinkedIn, went through six rounds covering DSA, system design, technical communication, and a hiring manager discussion, but was ultimately rejected.
How it went
Round 1 (DSA)
Introduction
Problem : Kadane's Algorithm (similar)
Work Overview
Solved it in time.
Round 2 (DSA)
Introduction
Leetcode : https://leetcode.com/problems/open-the-lock/
(Instead of BFS, I mistook it to be DP and was contiuously working towards memoization. In the last 7 minutes I was told I was in wrong direction, and I quickly tok the hint and solve it, although couldn't code because of time constraints)
Round 3 (DSA)
Introduction
2 DSA problems
Longest Palindromic Subsequence
https://leetcode.com/problems/minimum-window-substring/
Solved both the questions in time with coding.
Round 4 (System Design)
Introduction
LinkedIn Type Ahead System
Covered all aspects of HLD, the interviewer seemed satified and happy. ALthough he gave me a bad rating(got it from the recruiter and I still dont know what was wrong because it went super good. I could answer all his questions well)
Solved it in time.
Round 5 (Technical Communication)
Introduction
Past Project Discussion
Went great.
Went great
Round 6 (HM Round)
