I applied through university. The process took 2 days. I interviewed at Walmart (Bengaluru) in July 2019
Interview
It consisted of 3 technical round + 1 managerial round + 1 HR round.
First round was conducted on hacker rank. And some 30 were shortlisted for next round.
Package offered was 18.5 lpa.
Interview questions [5]
Question 1
first technical round consisted of 25 mcqs ( from os,java,oops , database, aptitude) + 1 coding question.
you have to complete it within 1 HR.
2 nd tech round - (60 min)
1. remove duplicate in linked list (write code)
2. first non repeating char in string (code)
3.discussion about hashmap and internal implementation
4. discussion about hashcode() and equal method in java.
5. questions on java collections
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.
