Walmart Software Engineer interviews reported here vary by team and role, but the recurring pattern is broader than a single algorithm screen. Candidates describe recruiter or HR contact followed by technical interviews that may combine coding with discussion of prior projects, system design, and manager or behavioral conversations. Some candidates reported a Karat assessment, while another experienced a lighter process without live coding or a formal assessment.
For coding, prepare to explain implementation choices as you work. Reported prompts include implementing a custom HashMap with collision handling, checking whether two strings are anagrams, building a BST, coding binary search, parsing instructions to identify qualifying rooms, and implementing an abstract method in another class. Clarify requirements before coding, describe the data structure you choose, and check the implementation carefully when the environment does not allow normal execution support.
Practical engineering discussion also appears in several accounts. One candidate encountered Core Java questions, while others were asked about backend languages, React Native experience, or the architecture of recent projects. Some processes included a system-design conversation, but another successful candidate reported only high-level technical discussion, so design should be treated as team-dependent rather than universal.
Behavioral preparation should cover project ownership, teamwork, workplace disagreement, difficult situations, career goals, and why the role fits. The number and order of interviews vary across these reports, so use the recruiter or hiring-manager conversation to confirm the format for the specific team.

Real interview reports from people who went through the Walmart process.
The assessment was a HackerRank Full Stack Engineering assessment with three sections. The first section was a language-agnostic software fundamentals/coding problem. The second was a frontend development task where I had to work with an existing Angular application and implement the required functionality, including search, sorting, data flow between components, and handling the no-results state. The third section focused on backend development. One interesting part was that the platform had a built-in AI Assistant that could be used during the assessment. It wouldn’t directly provide solutions, but it could inspect the project, explain unfamiliar concepts and syntax, clarify errors, and help understand the existing codebase. The frontend portion had automated tests as well, so I could run the test suite while working and verify the implementation against the requirements.

Synthesized from candidate reports. Individual experiences may vary.
Candidates commonly report an initial recruiter or HR conversation covering background, interest, availability, location, and fit. Some candidates then moved directly to a hiring-manager conversation, while others were scheduled for an assessment or technical screen.
Candidates report Karat, Glider, HackerRank, timed online assessments, and live video coding in different processes. Reported work includes data structures and algorithms, backend topics, and explaining a solution aloud; the assessment vendor and format are not consistent.
Reported technical questions range from HashMap, LRU cache, graphs, strings, trees, and arrays to Java, Spring Boot, concurrency, and resilience topics. Candidates may be asked to code, discuss a prior project, and explain complexity or design trade-offs in the same conversation.
Some candidates report a separate system-design or object-oriented design discussion, including inventory, contact-tracing, or Uber-like services. Other reports did not include a formal design round, so confirm whether design is part of the loop for the specific team.
Candidates report manager or behavioral conversations about previous systems, difficult workplace situations, teamwork, customer scenarios, and motivation for Walmart. A manager discussion may be mainly conversational, though one candidate reported unexpected design content in a round described as behavioral.
