Top Linked List Questions Asked in Microsoft Interviews
Linked List is one of the fundamental data structures frequently tested in Microsoft software engineering interviews. These problems evaluate a candidate’s understanding of pointer manipulation, memory handling, and efficient traversal techniques.
Many interview questions involve operations such as reversing a linked list, detecting cycles, merging lists, and finding middle elements. Mastering these patterns helps candidates write efficient solutions and handle edge cases confidently during technical interviews.
In this guide, we have compiled some of the most frequently asked Linked List LeetCode questions reported in Microsoft interviews. The list includes each problem’s difficulty level, interview frequency, and a direct link to the LeetCode problem, making it easier for you to start practicing.

How to Prepare for Linked List Questions in Microsoft Interviews
To perform well in Microsoft coding interviews, it’s important to understand common Linked List problem-solving patterns rather than memorizing solutions.
Some important strategies include:
- Practicing fast and slow pointer techniques
- Understanding how to reverse linked lists efficiently
- Learning to detect cycles using Floyd’s algorithm
- Solving problems involving merging, splitting, and reordering lists
Consistent practice with real interview questions will improve your problem-solving speed and ability to handle pointer-based problems, which are commonly asked in coding interviews.
