I applied online. The process took 2 months. I interviewed at Walmart (Bentonville, AR) in Dec 2021
Interview
So for me I was a new grad so the swe 2 was the only option. And I rate this interview process as bad because there was an unclear communication of what the interview was. So the actual time table from when you passed the assessment to the decision for an offer was like 2.5 months for me. But during that time they said it would take a month for the whole thing to happen. Then for me I had an assessment, a technical take home interview, and then a behavioral (at least thats what I was told). The assessment and take home interview were fine. But the last interview, I was told that it would be behavioral and no technical questions would be asked. But the engineer I was interviewing with just asked me a system design question and asked me to code it, which threw me for a loop, since they said that there wouldn't be technical questions.
Interview questions [1]
Question 1
The take home just asked to make like a profile using a front end language (javascript or react). The backend question was about a movie theater and a queue system.
The final round asked me to implement and code the product recommendation system for their website.
Looking back, I feel like I gained a clearer understanding of the process, even though I ultimately turned down the offer. The technical rounds were straightforward, featuring an implementation question on an LRU cache and a system design question about a rate limiter for an API. What helped me a lot was the walkthroughs for system design I went through on PracHub, which made those types of questions feel familiar. Overall, it was an easy experience, but I just didn't feel it was the right fit for me.
Interview questions [2]
Question 1
Implement an LRU cache with O(1) get and put using a hash map plus doubly linked list
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.
