I applied through an employee referral. The process took 2 weeks. I interviewed at Walmart (Bengaluru) in Jun 2015
Interview
Applied through a referral. I had a telephonic screening first. Then I was called on site for an interview.
The interviewers are intimidating and do not make the interview a pleasant experience. They bombard you with questions and the moment they realize something you've answered is partly incorrect, it's their field day. This is mostly true with the lower ups than the higher ups. Interview level gets better with higher ups. Also, the engineers keep switching language to Hindi so it can through you off your game. They don't clarify doubts or questions, instead ask you to look it up yourself. I could sense the air of haughtiness with the interviewers, especially the lower ups.
Overall a long, 5 hour negative experience where no one keeps up time. Plus side is the free food.
Interview questions [1]
Question 1
Data Structures and Algorithms - Trees, Arrays
Left side view of a tree, maximal element of array without any auxiliary space and such. They always want optimization at every step possible. And there's no time to solve the question, they keep asking you further questions. It's simply a case of whether you get it right in the first go or not.
OOP -Conceptual
Databases
System level understanding of their work
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.
