Question

Walmart | Interview Experiences | SDE 3 | 2022 | Set - 19

Answer 1

Walmart SDE-3 : - 

Last week i had the virtual interviews for Walmart Labs Bangalore, there were a total of 3 technical rounds.

 

1. 1st round : (DSA)

 

Questions : (LC Easy & Medium)

 

• Climbing stairs (https://leetcode.com/problems/climbing-stairs/) LC Easy
• Rotting Oranges (https://leetcode.com/problems/rotting-oranges/) LC Medium

 

Since i had already seen the problems i could easily provide and explain the most optimal solutions for them in under an hour.

 

1. 2nd round : (Core Java)

 

It was a stress round in some sense, questions revolved mostly around Generics, Threadpools, Concurrency, Multiple inheritance with interfaces and default methods and Hashmap.

 

1. Hiring manager round

 

Given a LLD problem to design a Retail POS system to evaluate the balance to be provided back to the customer during the billing, had to take into consideration different currencies ( as in balance can be provided back in multiple type of currencies) and denominations for each kind of currency, design should follow SOLID principles and have good performance.

 

I belived the hiring manager round did go well but got rejected after the final round. Will try again after the cool down period is over.

 

This is my first post on discuss section for interviews so if i have missed something please let me know so i could answer that in comments or add it here.
