I applied through college or university. The process took 1 day. I interviewed at Walmart (Provo, UT) in Sep 2017
Interview
Frustrating experience. I had heard good things about Walmart Tech, so I stopped by their booth at a career fair and I was asked to interview later that day. Details of what position the interview specifically for were not made clear, but I figured I could learn more in the interview. When I arrived for the interview, I waited for a half hour past my scheduled time before they realized that the recruiter I was supposed to interview with had accidentally overbooked. So they sent me into a room with a random guy. He didn't know what he was specifically interviewing me for, didn't even ask for my resume, and went an half hour over my allotted time asking different coding questions. Some questions weren't clear, and I did not know what he was trying to ask at times. Needless to say, I came out very frustrated with the process, especially since I had rearranged my schedule for this.
Surprisingly easy-going for a big name like Walmart. The interview started with a simple coding challenge focused on detecting cycles in directed graphs. I felt pretty relaxed during the technical rounds, which were straightforward and conversational. The wild part was recognizing the question as a close variant of one I had practiced on PracHub just days earlier. It definitely boosted my confidence. Overall, I was impressed with the process and was thrilled to receive an offer, which I happily accepted.
Interview questions [1]
Question 1
Course Schedule (detect a cycle in a directed graph using topological sort / DFS)
First, standard short phone call with recruiter. Then a 1-hour interview with an engineer on the team, asked about technical experience and background, and did a live coding assessment via video call. Fairly standard Leetcode style questions
Intense but rewarding — the interview for the Software Engineer position at Walmart Labs was tougher than I anticipated. The technical rounds included an LRU Cache implementation question where I had to articulate my design thoughts on thread safety, followed by a complex system design for a real-time inventory service. What made a difference in my prep were the company-specific prompts I found on prachub.com; they really helped me understand the types of questions I might face. Despite the challenging nature of the interviews, I ultimately received an offer but chose to decline.
