Walmart Interview Questions
Overview
Section titled “Overview”Walmart’s India tech hiring runs through Walmart Global Tech - its engineering organisation for e-commerce, supply chain, and enterprise platforms - via a 4-stage DSA-plus-system-design loop that mirrors other large product companies, not a retail-store process.
Walmart interview process at a glance
Section titled “Walmart interview process at a glance”| Round | Duration | What they test |
|---|---|---|
| Online Assessment | 90 min | ~25 CS-fundamentals MCQs + 2 DSA problems (LeetCode Medium) |
| Technical Round 1 | 45-60 min | DSA (1-2 problems) + OOPs + SQL |
| Technical Round 2 | 45-60 min | Low-level/object-oriented design + project deep-dive |
| HR | 20-30 min | Behavioural + culture fit |
Online Assessment
Section titled “Online Assessment”A 90-minute timed screen on HackerEarth or HireVue mixing CS-fundamentals MCQs with 2 DSA coding problems at LeetCode-Medium difficulty. This is the highest-volume filter in the process - clean, fully-passing solutions matter more than clever partial ones.
Common questions
- IPv4-address validation - return a boolean array marking each address valid/invalid
- Rain-water-trapping style array problems
- DFS-based grid/graph traversal problems
- CS-fundamentals MCQs on OOPs, DBMS, and OS basics
Technical Round 1
Section titled “Technical Round 1”A 45-60 minute DSA-focused round (often on HirePro) that opens with a short introduction, then moves into 1-2 medium-level coding problems, followed by OOPs and SQL questions.
Common questions
- Top-K frequent elements - expects heap or bucket-sort approach
- Shortest path in a grid - expects BFS
- Find the second-highest salary in an employee table (SQL)
- OOPs fundamentals - polymorphism, inheritance, and where you’ve applied them
Technical Round 2
Section titled “Technical Round 2”Shifts from pure coding to low-level/object-oriented design plus a detailed project discussion. For freshers this stays at OOD and basic database-schema-modeling depth rather than full high-level architecture; domain chat around inventory, cart/checkout, or search is common.
Common questions
- Design the classes for a small system (e.g. a shopping cart or inventory service)
- Merge overlapping delivery-slot intervals - expects an interval-merge approach
- Walk through your project’s architecture, the hardest bug you hit, and what you’d rebuild
- Discuss inventory or cart/checkout bottlenecks and failure modes in plain language
Round-by-round narratives are on the Walmart interview experience page.
HR / managerial round
Section titled “HR / managerial round”A closing 20-30 minute conversation on motivation, ownership, and logistics (relocation to Bangalore or Chennai, notice period). Concrete, results-oriented answers outperform generic slogans.
Common questions
- Tell me about yourself and why Walmart
- Tell me about a time you helped a customer or teammate even though it wasn’t strictly your job (servant leadership)
- How would you balance cost efficiency with a good customer experience in a large-scale retail operation?
- Working with unclear requirements - walk me through an example
Sample answer frameworks for each of these are on the Walmart HR interview questions page.
Walmart Global Tech vs retail hiring
Section titled “Walmart Global Tech vs retail hiring”Walmart’s India engineering hiring goes through Walmart Global Tech (Bangalore, Chennai), which builds the e-commerce, supply chain, and enterprise software used across Walmart and Sam’s Club - a DSA-plus-system-design loop like Amazon or Flipkart’s. This is entirely separate from Walmart’s retail/store-associate hiring in the US, which does not run a technical interview process. If you’re prepping from this page, you’re prepping for the Global Tech software track.
Frequently asked questions about Walmart interviews
Section titled “Frequently asked questions about Walmart interviews”What is the Walmart interview process for freshers?
Walmart Global Tech India’s SDE process usually runs 4 stages: 1. Online Assessment (90 min) - roughly 25 CS-fundamentals MCQs plus 2 DSA coding problems (LeetCode Medium), on HackerEarth/HireVue. 2. Technical Interview 1 (45-60 min) - 1-2 more DSA problems plus OOPs and SQL. 3. Technical Interview 2 (45-60 min) - low-level/object-oriented design and a detailed project discussion. 4. HR / hiring-manager round (20-30 min) on motivation, ownership, and fit. Total timeline is roughly 3-6 weeks.
Is Walmart’s India hiring for retail store jobs or software roles?
This page covers Walmart Global Tech India - the engineering org behind Walmart’s e-commerce, supply chain, and enterprise platforms, based mainly in Bangalore and Chennai. It hires SDEs through a DSA-plus-system-design loop similar to other product companies, not through retail/store-associate hiring, which runs a completely different process.
What questions are asked in Walmart interviews?
Reported coding questions include an IPv4-address-validation problem (return a boolean array marking each address valid/invalid), the rain-water-trapping problem, DFS-based grid/graph problems, Top-K frequent elements (heap/bucket sort), and shortest path in a grid (BFS). SQL questions like finding the second-highest salary in a table are common, alongside OOPs fundamentals. Later rounds bring domain discussion around inventory, cart/checkout, and search.
How many rounds are there in the Walmart interview?
Typically 4: an Online Assessment, two Technical Interviews (the first DSA-heavy, the second leaning into LLD/system design and project depth), and a closing HR/managerial round. Some drives compress this to 3 rounds or fold HR into the final technical round.
How should I prepare for Walmart interviews?
Drill LeetCode Medium-level DSA (arrays, graphs, intervals, heaps) since both the OA and Technical Round 1 lean on it. Revise OOPs and SQL - second-highest-salary-style queries come up often. For the design round, freshers get object-oriented/LLD questions (class design, basic DB schema) rather than full HLD, so practice designing a small system (e.g. a cart or inventory service) end-to-end. Keep one detailed project story ready for stack choices and the hardest bug you debugged.
What does Walmart Global Tech pay freshers in India?
Candidate reports put SDE-1 packages roughly in the ₹18-25 LPA range (base plus stock), though this varies by year, college tier, and role. Confirm the exact figure on your offer letter rather than relying on aggregated reports.
