What is the Walmart Global Tech SDE campus process?

Typical loop: online assessment (technical MCQs on OOP/OS/DBMS/Networks/SQL plus 1-2 coding problems), then 2-3 technical interviews (core CS and/or DSA), then managerial/HR. 2025-26 contest-style drives have listed 25 MCQs in 25 minutes and 2 coding problems in 90 minutes. CGPA filters often require 7+.

What DSA does Walmart ask?

Reported problems: maximum size rectangle of 1s in a binary matrix, Kadane variant with max sum less than K, modified Dijkstra for multi-train routing with times, Dutch national flag, Pascal triangle, longest subarray sum divisible by K, stack using queues, interval merging for free slots, tree distance via BFS.

Do Walmart interviews focus more on core CS or coding?

Both appear. Some Round 1 panels are pure core CS (SQL command types, OSI walkthrough of sending a WhatsApp message) with no live coding; Round 2 then goes deep DSA. Other drives code in every technical round.

What packages/stipends are reported?

A 2025-26 campus notification cited summer internship stipend around ₹1.1 lakh/month for eligible batches. FTE bands vary - treat official offers as authoritative.

Walmart Interview Experience 2026

Overview

Walmart Global Tech India campus hiring mixes fundamentals MCQs with medium DSA and long technical conversations. Notes below are synthesized from public 2024-2025 on-campus reports into round tables and outcome notes - treat this as a prep map, not a script.

How Walmart Global Tech campus loops differ from pure startup SDE

Assessment vendors (e.g. HirePro in some reports) can change section mix by year.
Intern+FTE packages may add or reorder rounds versus full-time-only drives.
Managerial/HR still probes communication and location after technicals.
Scale/retail context helps motivation answers but does not replace DSA fundamentals.

Round-wise process at a glance

Round	Typical format	What clears you
OA MCQ + coding	~22-25 CS MCQs + 1-2 coding (35-90 min windows vary)	Strong OOP/OS/DBMS MCQs + clean coding ACs
Technical 1	1-1.5 hrs	Core CS depth and/or DSA
Technical 2	1-1.5 hrs	Harder DSA + OS/OOP/SOLID
Managerial / HR	Behavioural + projects	Ownership stories; internship depth

Technical interview experience 1 - SDE on-campus 2024 (physical)

Technical interview experience 1

Candidate profile: Walmart Global Tech campus Aug 2024 physical drive (GFG). OA then three interview rounds.

22 technical MCQs: OOP, OS, DBMS, Networks, SQL (~35 min)
2 easy-medium coding problems (~40 min)

Technical 1 (~1-1.5 hrs, SDE3 interviewer)

No live coding in this account - core CSE focus
SQL command types (DDL/DQL/DML/DCL/TCL) with examples
Computer networks: what happens when you send a WhatsApp message - full OSI walkthrough

Technical 2 (~1.5 hrs, senior engineer)

Deeper technical grilling (report emphasises senior panel)

Round 3

Scheduled as short HR but ran ~1.5 hrs for some; 10 candidates reached this stage in the report
Results announced same evening with selects

Takeaways

What decided it: Strong OOP/OS/DBMS/SQL MCQs on OA, then a long Round 1 on SQL command types and a full OSI WhatsApp walkthrough without live coding.
Common fail: Skipping networks theory because you expected only DSA; fading in a 1.5-hour “HR” that was still evaluative.
How to practise: OSI end-to-end story for messaging; DDL/DML/TCL examples aloud; timed MCQ+coding OA.

Technical interview experience 2 - SDE HirePro / Intern+FTE patterns

Technical interview experience 2

Candidate profile: Composite of HirePro campus and March 2024 Intern+FTE reports.

OA themes

HirePro ~90 min: OS, DBMS, OOP, DSA MCQs + 2 coding
HackerEarth Intern+FTE example: 114 appeared / 90 min

DSA prompts reported

Max rectangle of 1s in binary matrix
Kadane with constraint sum < K
Multi-train Dijkstra with arrival/departure times
Dutch national flag; Pascal triangle; longest subarray sum divisible by K
Stack using queues; free-slot interval merge; binary-tree node distance (BFS)

Core + managerial

Java diamond problem / multiple inheritance; SOLID; virtual functions
Semaphores, mutex, deadlock; segmentation vs fragmentation; compaction
Normalisation through BCNF; transaction anomalies; keys
Internship leadership behavioural questions

Takeaways

What decided it: Switching cleanly between HirePro DSA (matrix rectangle, Dijkstra variants) and textbook OS/DBMS/SOLID in consecutive rounds.
Common fail: One strong coding round then shallow deadlock/normalisation answers.
How to practise: Alternate days: medium DSA then OS/DBMS sheet; one internship ownership STAR.

Technical interview experience 3 - SDE Intern + FTE (March 2024, college hiring)

Intern + FTE composite drive

Source: interviewexperiences.in March 2024 Walmart India hiring report. Same-day technical stacking; HR next day.

Online test (prior day)

HackerEarth-style timing; large cohort (~114 candidates in one report)
CS MCQs plus coding - details vary by mail

Technical 1 (Zoom, morning)

Binary tree distance / traversal-style question
“What happens when you type www.google.com?” networking walkthrough
Hub vs switch, impairment concepts (candidates report struggling here)
SQL vs NoSQL with examples
Index shifting: multiple range updates on a subarray

Technical 2 (same afternoon, new interviewer)

Stack using queues
Interval merge: find slots where three students are free
Normalization through BCNF
OOP live code: Shape / Rectangle / Square
Virtual functions, static vs dynamic binding

HR (next day)

Experienced HR panel (~15+ years cited)
Outcome split: 10 FTE + internship, 14 internship-only from 24 HR attendees in the report
Leaving the Zoom early was cited as a risk factor for FTE vs intern-only outcomes

Key takeaways: Walmart may stack two heavy technicals in one day - conserve energy. Networking “type a URL” questions appear alongside DSA. Stay on the call until HR formally closes the session.

HR / managerial notes

HR interview experience

Focus on internship ownership, teamwork, why Walmart Global Tech, and location (Bengaluru/Chennai commonly listed). Keep project demos (GitHub video) ready when invited.

Sample answers for high-frequency questions

Q. What happens when you send a WhatsApp message (OSI lens)?
A. Walk application (message compose) → presentation/session concepts → transport (TCP) → network (IP routing) → data link/physical on Wi-Fi/cellular. Mention encryption at app layer and store-and-forward via WhatsApp servers without claiming internal proprietary detail.

Q. Max rectangle of 1s in a binary matrix.
A. Treat each row as histogram base using consecutive 1s heights; largest rectangle in histogram via stack per row. O(rows × cols).

Q. SQL command categories.
A. DDL define schema (CREATE/ALTER/DROP); DML modify rows (INSERT/UPDATE/DELETE); DQL retrieve (SELECT); DCL rights (GRANT/REVOKE); TCL transactions (COMMIT/ROLLBACK/SAVEPOINT).

Q. Stack using queues.
A. Two-queue or one-queue approaches: make push costly (enqueue then rotate) or pop costly. State complexity of each operation.
