This guide helps candidates prepare for interviews with Walmart Global Tech, Walmart’s technology division, formerly known as Walmart Labs. Walmart Global Tech works across retail, global supply chain, and e-commerce technology. ![Walmart building](https://storage.ghost.io/c/a5/f5/a5f5c2f0-4c62-43c7-891b-662a0b6d68b3/content/images/2025/01/Walmart-building.jpg) *Christy Umberger • Last updated a month ago* ## Walmart interview process The process typically takes **4–8 weeks** and usually includes: 1. Recruiter phone screen 2. Technical screen 3. Final round Learn more about [Walmart Global Tech](https://www.aced.io/companies/walmart-labs?ref=exponent-blog.ghost.io). ### Recruiter phone screen The first step is a recruiter phone call. Prepare to discuss your previous roles and experience, along with a couple of basic technical questions related to the position. Bring questions about the role, team, logistics, and the remainder of the interview process. ### Technical screen Engineering candidates generally complete a **one-hour HackerRank coding challenge** with **1–2 medium-to-hard questions**. Topics may include Python, SQL, data structures and algorithms, arrays, and binary search. Prepare with our [software engineering interview course](https://www.aced.io/courses/software-engineering?ref=exponent-blog.ghost.io) and [data structures and algorithms guidance](https://www.aced.io/courses/software-engineering/swe-practice/swe-tips?ref=exponent-blog.ghost.io). For non-engineering roles, the assessment is domain-specific: - Data roles: SQL and statistical analysis, including our [SQL interview guidance](https://www.aced.io/courses/data-science/sql-interviews/how-to-answer-sql-interview-questions?ref=exponent-blog.ghost.io). - Product management roles: a case study or product strategy questions, supported by our [product strategy guidance](https://www.aced.io/courses/pm/product-strategy/how-to-answer-product-strategy-questions?ref=exponent-blog.ghost.io). ### Final rounds Final interviews typically include **3–5 loops**, depending on the role. Each loop lasts **one hour**, is virtual, and is conducted one-on-one with an interviewer. Expect several technical rounds focused on role-specific knowledge. Most candidates also encounter a case study involving practical, day-to-day team problems. Every role includes a behavioral interview with a hiring manager, often focused on past projects and soft skills. ## Top Walmart interview questions The following are examples of interview questions reported by candidates.
