I interviewed at Walmart (Sunnyvale, CA) in Jan 2025
Interview
in format of tech, bq, about 30 min, 3 rounds, solve leetcode, ask about work exp, resume, tech stack on resume, used tech stack, kafka, k8s, java spring boot. interviewer was very nice and speak clearly.
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
