Was a position for a javascript role a few years back. Had a great 30 minute conversation with a recruiter. Had crushing, painful experiences with managers and getting ripped off at prior jobs. Was looking for new work after a period of a year and half. She treated my gap in unemployment as if it was a thing. I was on GitHub making my skills better. But that cold, corporate fact meant more to her than my character, skills, and passion I have in Walmart. I thought I was having a conversation and getting through to this person. I thought these guys were innovators with a startup ethos. They're cutthroat bureaucrats to the bitter end. So disappointed.
Interview questions [1]
Question 1
After a great 30 minute interview with a thick, hearty resume of accomplishments but a gap in my resume: Explain the gap in your resume.
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.
Interview questions [2]
Question 1
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.
