Me postulé a través de una facultad o universidad. El proceso tomó 3 semanas. Acudí a una entrevista en Walmart (Reston, VA) en oct 2018
Entrevista
Before going to on-site interview, there was a homework designing Drone Delivery System. On the onsite interview, first round is manager interview, second round is Tech interview, which let me explain the Drone Delivery System.
Instead of discuss with you, the manager challenge you a lot, with aggressive attitude.
The design part, the design granularity is very unclear, which make the whole process very dizzy.
Preguntas de entrevista [1]
Pregunta 1
Q1: Describe a project
Q2: Explain your drone delivery code.
Q3: How to add a battery function to your designed drone.
Looking back, I feel like I gained a clearer understanding of the process, even though I ultimately turned down the offer. The technical rounds were straightforward, featuring an implementation question on an LRU cache and a system design question about a rate limiter for an API. What helped me a lot was the walkthroughs for system design I went through on PracHub, which made those types of questions feel familiar. Overall, it was an easy experience, but I just didn't feel it was the right fit for me.

Implement an LRU cache with O(1) get and put using a hash map plus doubly linked list
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.
