What Is the Microsoft SDE Online Assessment?

The Microsoft SDE Online Assessment consists of two primary components:

  • Coding Assessment: A timed programming test with two coding problems to be solved in 90 minutes.
  • Video Interview: A recorded interview designed to assess your soft skills, cultural fit, and personality.

This dual-format evaluation ensures Microsoft can comprehensively assess a candidate’s technical aptitude and suitability for the role.


Microsoft SDE Coding Assessment

The coding portion of the assessment tests your ability to solve algorithmic and data structure-related problems efficiently and accurately. The questions are typically of easy to medium difficulty and are structured to evaluate the following key skills:

  • Problem Statement Retention: Your ability to read and fully understand the requirements of a coding problem.
  • Coding Ability: Translating a problem’s solution into accurate, functional code.
  • Data Structure Application: Applying appropriate data structures (e.g., arrays, lists, maps, sets) to solve problems effectively.
  • Runtime Complexity: Analysing and improving the time and space complexity of your solutions.
  • Simplification: Breaking down complex problems into simple, logical steps that can be easily understood.
  • Optimisation: Identifying and achieving the most efficient solution for a given problem.

Microsoft SDE Coding Sample Questions

1. Determine if Two Trees are Identical (Easy)

Given two binary trees, the task is to find if both of them are identical or not.

Example 1: 

Input:

    1           1
   / \         / \
 2     3    2    3

Output: Yes

 

Example 2: 

Input:

    1           1
   / \         / \
 2     3    3    2

Output: No


2. Kadane's Algorithm (Medium)

Given an array Arr [] of N integers. Find the contiguous sub-array (containing at least one number) that has the maximum sum and return its sum.

Example 1:

Input:
N = 5
Arr[] = {1,2,3,-2,5}
Output: 9

 

Example 2:

Input:
N = 4
Arr[] = {-1,-2,-3,-4}
Output:
-1
