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!
