Microsoft interview questions are designed to identify candidates who can add value to the company in the key knowledge areas of product development, design, and coding. Microsoft interview questions are comparable to FAANG interview standards. This means they can be quite challenging without the right skill, expertise, and interview preparation. 

Microsoft interview questions are also role and company-specific based on Microsoft’s core competencies and culture. Below are commonly asked questions at Microsoft’s tech interviews, including Microsoft coding interview questions and Microsoft behavioral interview questions. 

If you are preparing for a tech interview, check out our technical interview checklist, interview questions page, and salary negotiation e-book to get interview-ready!

Having trained over 11,000 software engineers, we know what it takes to crack the toughest tech interviews. Our alums consistently land offers from FAANG+ companies. The highest ever offer received by an IK alum is a whopping $1.267 Million!

Microsoft’s Core Competencies

Microsoft interview questions are based on Microsoft’s six core competencies which are listed on the company’s career page as given below:

  1. Adaptability for agile problem-solving
  2. Collaboration through inter/Intra team communication
  3. Customer-oriented  approach by empowering employees
  4. Creating impact through influence through effective communication
  5. Result-driven approach emphasizing accountability and striving for excellence
  6. Judgment, i.e., knowledge-based decision making to resolve complex problems

Microsoft Technical Interviews Key Areas of Assessment

Microsoft interview questions are designed to assess candidates for technical excellence across all stages of the engineering life cycle. At a Microsoft technical interview, you will be assessed on the following areas:

  • Coding: Microsoft coding interviews are the most important round of the entire interview process. You will be assessed on core coding concepts and your ability to write clean, clear code. At Microsoft, you will compile and run code on a third-party coding platform using a coding language of your choice.
  • Design: You’ll be assessed on your ability to design and develop both existing and new platforms.
  • Problem-solving: Microsoft interviewers will be keen to understand your approach to developing solutions, including how you view problems from different perspectives and seek information needed to arrive at a solution.
  • Testing: You’ll be expected to test your solutions to show your code is effective. You will be assessed on your ability to test code consider corner cases, errors, boundaries, and security features.

Microsoft Interview Questions on Data Structures and Algorithms

Microsoft interview questions assess your understanding of the benefits of the different data structures and algorithms, their applications, and how to choose the right ones to develop solutions to coding problems.

Microsoft coding interview questions focus on key data structures and algorithms topics — arrays, strings, linked lists, recursion, sort, search, hash maps, trees, graphs, dynamic programming, math, statistics, etc.

Linked Lists

  • Reorder the singly linked list L: L0 → L1 → … → Ln-1 → Ln to L0 → Ln → L1 → Ln-1 → L2 → Ln-2 → …
  • Clone a linked list with next and arbitrary (or random) pointers.

Arrays

  • Given an array where every element occurs three times, except one element, which occurs only once, find the element that occurs once. The expected time complexity is O(n) and O(1) extra space.
  • Given an unsorted integer array, find the smallest missing positive integer. Run the algorithm in O(n) time using constant extra space. 

Trees

  • Given two values, k1 and k2 (where k1 < k2) and a root pointer to a Binary Search Tree. Print all the keys of the tree in range k1 to k2. 
  • Given a binary tree of size N and an integer K, print all nodes at distance k from root (root is considered at a distance 0 from itself). Nodes should be printed from left to right. If k is more than the height of the tree, nothing should be printed.

Dynamic Programming

  • Given n non-negative integers representing an elevation map where the width of each bar is 1, compute how much water it can trap when it rains.
  • Given a set of two integers, check if it can be divided into two subsets with equal sum.

Graphs

  • Given a directed, acrylic graph of N nodes, find all possible paths from node O to node N-1, and return them in any order.
  • Given an ancient dictionary with alphabetically ordered words, order the words correctly according to the ancient language.

Strings

  • Given a string ‘str’ of digits, find the length of the longest substring of ‘str’, such that the length of the substring is 2k digits and the sum of left k digits is equal to the sum of right k digits.
  • Given a string A representing an absolute path for a file (Unix-style). Return the string A after simplifying the absolute path.

Search

  • Write an efficient algorithm that searches for a value in an m X n matrix. Integers in each row are sorted from left to right, and the first integer of each row is greater than the last integer of the previous row.
  • Given a rotated array that is sorted, search for an element in it.

Sort

  • Merge K sorted arrays ‘arr’ of size N each into a new array ‘res’, such that ‘res’ is a sorted array.
  • Sort a given array of integers using the merge sort algorithm. Input Format: The function contains a single argument, an integer array arr; Output Format: Return the sorted integer array.
