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.
