J'ai postulé via un établissement d'enseignement supérieur ou universitaire. Le processus a pris 6 semaines. J'ai passé un entretien chez Walmart (Bentonville, AR) en nov. 2020
Entretien
Abysmal. Interviewers were late (once it was a no-show), didn’t care, and no chance for me to interview them. The questions were fairly simple, however. Mostly DSA trivia based and 1 take home assignment. Everything ran slow.
Ghosted after on-site, 1 month later I get a text with the offer and then 2 weeks later the email. Insultingly low salary (70k) with crappy benefits.
Overall, waste of time interviewing here. If you’re reading this, you can do better.

Question 1
Scalability questions. How would you modify your code for given constraints, etc. easy if you have a grasp on CS fundamentals.
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.

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.
