Walmart SDE - 3 interview experience
Summary
I recently interviewed for an SDE-3 position at Walmart, clearing the first DSA round but failing the LLD round due to a lack of strong design fundamentals, which ultimately led to me not qualifying for Round 3.
Full Experience
Recently I interviewed for SDE-3 at Walmart. I am sharing my experience in case it helps others.
Round 1 – DSA
Q1: Next Greater Element II
Q2: A grid-based problem similar to Walls and Gates / Rotting Oranges (classic BFS pattern)
➡️ I got confirmation from the recruiter that I cleared Round 1.
Round 2 – LLD + Java
This was my first Low-Level Design round, and honestly, I didn’t perform well here.
I was able to answer Java and Spring Boot–related questions confidently.
However, my LLD approach and structuring were not strong enough.
❌ I didn’t qualify for Round 3.
