I applied through college or university. The process took 2 months. I interviewed at Walmart (Dallas, TX) in Dec 2018
Interview
Multiple stages going from on campus screening interview, phone interview, and then Onsite in Dallas, TX in Walmart Technology division. Took about 2 months as they had to schedule everything. Generally, easy interview with questions about my resume, 2 whiteboarding questions and then they treat you to lunch afterward. They are a division of Walmart that is separate from the corporate as it is a bunch of engineers. They were very friendly and have an open workplace (no cubicles). They gave me the official written offer the next day but I turned it down.

Question 1
ReactJs general questions. Write a function that gives me the Fibonacci sequence.
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.

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.
