Walmart Data Analyst reports describe several possible interview paths rather than one fixed sequence. Introductory calls commonly cover background, career goals, interest in Walmart, resume experience, and sometimes salary expectations or SQL experience. Prepare a concise introduction that connects a relevant analysis project or programming experience to the role.
Manager and team conversations can focus on how you approach analysis in practice. Reported prompts include explaining the first steps in a new analysis, discussing a relevant technical project, and proposing metrics and a monitoring approach for another company’s performance. Build answers around the decision, the metrics, and the reasoning behind your choices.
Technical formats vary across reports. Candidates have described a HackerRank with SQL and Python questions, one or two LeetCode-style problems, and a CoderPad exercise on transaction data. In the CoderPad report, the candidate solved a fixed-size sliding-window problem and discussed using prefix sums for changing query lengths and the associated space trade-off. Practice explaining your approach while coding, including why you would revise it.
Behavioral discussions may cover stakeholder work, deadlines, large data volumes, strengths and weaknesses, or past projects. Use specific examples that show both your analytical contribution and how you communicated it.

The recruiter screen was easy — mostly logistics and a gut-check on why Walmart specifically. I said something about the scale of the inventory systems being a different kind of hard than anything I'd touched before, and that seemed to land fine.
The technical phone screen is where I started sweating a little earlier than expected. It was a coding round on CoderPad — a sliding window problem on a stream of transaction data, nothing exotic, but the interviewer kept nudging me to talk through the space complexity trade-offs before I'd even finished the happy path. I'm used to explaining my thinking as I go, but explaining it while also being pushed to optimize mid-stream threw off my rhythm for a good two minutes. I got there, but I remember thinking afterward that I should've just paused and re-planned out loud instead of trying to patch the solution live.
Questions asked: Technical phone screen (CoderPad):
The prompt was: "Given a stream of transaction amounts for a single customer account, find the maximum sum of any contiguous subarray of exactly length k, where k is provided as input. Then, as a follow-up, handle the case where k can change between queries without re-scanning the whole array from scratch."
The first part is a straightforward fixed-size sliding window — sum the first k elements, then slide by subtracting the outgoing element and adding the incoming one. I coded that part in about 5 minutes. The follow-up is where it got harder: they wanted a structure that could answer different k queries efficiently, which nudges you toward prefix sums instead of a pure sliding window. I proposed a prefix sum array so any range sum is O(1) after O(n) preprocessing, and they asked me to justify the space trade-off versus just re-running the window each time. That's the part I mentioned rattled me — explaining the trade-off while still finishing the code.

Synthesized from candidate reports. Individual experiences may vary.
Data Analyst candidates reported recruiter or HR conversations covering their background, career goals, interest in Walmart, resume details, and tell-me-about-yourself responses. One report also mentioned salary range and SQL experience. Prepare a concise explanation of relevant work and the tools you have used.
Technical formats varied across Data Analyst reports. Candidates described a HackerRank with SQL and Python questions, one or two LeetCode-style problems, and a CoderPad transaction-data exercise. In the CoderPad report, follow-up discussion covered prefix sums and space trade-offs after a fixed-size sliding-window solution.
Candidates reported meetings with a hiring manager or team members. Prompts included explaining a relevant technical project, describing first steps in a new analysis, and responding to a case about metrics and monitoring another company’s performance. Connect your proposed analysis to a clear business question.
Some reports included behavioral questions about stakeholder collaboration, deadline pressure, large data volumes, strengths, weaknesses, and prior projects. Prepare short examples with a clear situation, your analytical contribution, and how you communicated or acted on the result.
