I appeared for Walmart Senior Software Engineer (IN4) in April 2026 and here's the experience :
R1 (Coding) - Was able to solve both questions with optimal approach.
1. https://leetcode.com/problems/house-robber-ii/description/
2. https://leetcode.com/problems/search-in-rotated-sorted-array/description/
R2 (Project Discussion + LLD) - Went really well, was able to answer everything convincingly
1. https://leetcode.com/problems/lru-cache/description/
2. Discussion around common design patterns used in my own projects and how they're used. Strategy, Observer, Builder, Factory etc
3. Some HLD trade-off kind of discussion from my own projects discussion
R3 (System Design) - Design an E-commerce app which supports high scale and handles peak traffic surge scenarios during flash sale.
- Discussion went decent around trade offs in DB choices (SQL vs NoSQL, ElasticSearch for text search etc, handling concurrency with optimistic locking, how to reserve the inventory, preventing double ordering/payment etc). The interviewer himself didn't have much idea and was just playing around.
R4 (HM Round) - Typical Techno- managerial round with discussion on past projects and behavioral questions. Was able to answer everything well.
Final Verdict :- Got the offer after 2-3 days but the compensation offered was even lower than my current/previous one. The recruiter was extremely rude and acted with a "Take it or leave it" attitude.
I asked for extending the joining date by a week since I was in final stages of other companies but the bugger was too resistant even on extending that. I got offer from somewhere else and ended up rejecting this joke of an offer. Would have joined it in worst case anyway considering the current market but thankfully to god I got a better one somewhere else.
