I applied through university. The process took 1 day. I interviewed at Walmart
Interview
Some technology questions and some general personality questions. For technology, asked a lot about technologies I'd worked with and gave me a fairly straightforward coding challenge. For personality, asked a lot about specific scenarios (i.e. what if a team member was -, or how would you handle a situation where-). Gave me a pretty specific description of the job, including responsibilities and possible movement in the company, which was appreciated and answered a lot of questions. Overall, a pretty positive experience, with little pressure and a friendly, but businesslike atmosphere.
Interview questions [1]
Question 1
When was a time that you were asked to do something unethical?
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.
