Walmart SDE 2 Online Assessment (OA) Experience - September 2024
I recently appeared for the Walmart SDE 2 OA and wanted to share my experience. Here's a breakdown of the assessment pattern and questions:
Assessment Pattern:
25 MCQs covering the following topics:
- Programming Concepts (Data Structures, Algorithms)
- Operating Systems (OS)
- Object-Oriented Programming (OOP)
- Database Management Systems (DBMS)
- System Design
After the MCQs, there was a coding round with 2 coding questions. Below are the details:
Coding Round:
Question 1:
Problem: Reverse a given number, calculate the absolute difference between the reversed number and the original number, then count how many 2s are there in the factors of the absolute difference.
Steps:
- Reverse the number.
- Find the absolute difference between the original and reversed number.
- Count the number of 2s in the factors of the absolute difference.
Question 2:
Problem: You are given a string, and you need to print all the permutations that start with a digit.
Steps:
- Identify permutations of the string.
- Print the permutations that begin with a number.
Overall, the OA was a good mix of conceptual MCQs and interesting coding questions. Hope this helps others preparing for the Walmart SDE 2 role!
