10 Walmart Global Tech Software Engineer Intern Interview Questions (2026)
Walmart Global Tech's SWE intern loop in 2026 is a HackerRank and a 2-round virtual onsite with one technical and one behavioral. The intern bar is real but calibrated for undergrads, and intern-to-full-time conversion is a major hiring channel. Interns spend the summer on a team building real features at retail scale.

Loop overview
Intern candidates report a 4-7 week timeline in 2026, with applications opening in August. HackerRank (2 problems, ~75 minutes). Virtual onsite: one 45-minute technical (data structures, basic SQL, light system thinking), one 30-minute behavioral. Interns typically join a single team for 10-12 weeks and own a project with a manager and mentor.

Why do you want to intern at Walmart Global Tech?
Frequently askedOutline
Specifics: the engineering reinvention story, scale of the retail business, the breadth (e-commerce, supply chain, in-store, advertising). Avoid 'I want a stable big-company internship' framings.
Tell me about a project where you had to learn a new framework or language.
Frequently askedOutline
STAR. Show how you ramp — docs, mentorship, building toy projects. Walmart interns join teams using stacks they may not have seen. Show fast-learner signal.
Describe a time you got constructive feedback.
Frequently askedOutline
STAR. Show you take feedback seriously and act on it. Avoid 'I take feedback well' as the answer — give a concrete instance and what you changed afterward.
Tell me about a time you worked under tight time pressure.
Frequently askedOutline
STAR. Pick a hackathon, group project deadline, or internship sprint. Show how you prioritized, what you cut, and how you communicated risk.
Coding (LeetCode patterns) (4)
Implement a function that returns whether two strings are permutations of each other.
Frequently askedOutline
Hash map of char counts. Increment for one string, decrement for the other. All zero at end = permutations. Or sort both and compare (O(N log N) but simpler code). Edge case: length mismatch fast-fail.
Given a sorted array, return a balanced binary search tree from it.
Frequently askedOutline
Pick the middle element as the root. Recurse on left half and right half for left and right subtrees. O(N) time, O(log N) recursion stack. Result is height-balanced.
Implement a function to remove duplicates from a sorted array in-place.
Occasionally askedOutline
Two pointers. Slow pointer points to the next slot for a unique element; fast pointer scans. When values differ, write fast's value to slow+1 and advance slow. O(N) time, O(1) space. Return new length.
Find the contiguous subarray with the maximum sum.
Occasionally askedOutline
Kadane's algorithm. Track current subarray sum and best so far. If current goes negative, reset to 0. O(N) time, O(1) space. Edge case: all negatives — return the max element.
Technical (2)
Write a SQL query to count orders per status (pending, shipped, delivered, cancelled).
Frequently askedOutline
GROUP BY status, COUNT(*). Be ready for a JOIN-based variant if the schema has a separate status_lookup table. Discuss what happens when a status enum value has zero rows.
What's the difference between an ArrayList and a HashMap in Java?
Occasionally askedOutline
ArrayList: indexed, ordered list, O(1) access by index, O(N) lookup by value. HashMap: key-value pairs, unordered, O(1) average for get/put. Use ArrayList for sequences, HashMap for lookups by key.
