Candidatei-me por indicação de um funcionário. O processo levou 4 semanas. Fui entrevistado pela Walmart (Sunnyvale, CA) em jan. de 2015
Entrevista
Interview went smoothly. Standard technical questions with emphasis on database internals, object oriented design, java, big data technologies, data structures, algorithms, coding and presentation, problem solving etc. First there was a phone interview, followed by onsite interview. There were 4 interviewers and all were friendly with clear expectation set on solving the problem in efficient way. Efficient and structured code is expected and working internals of java and database is also expected along with few big data technologies
Perguntas de entrevista [1]
Pergunta 1
If tree 1 has millions of nodes, tree 2 has thousands of nodes. How will you find tree 2 is a subtree of tree 1? How sorting in database works?
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.
