Interview Process

The Microsoft Senior Software Engineer interview process generally includes a technical phone screen followed by an onsite interview. The first step was a technical phone screen lasting about 50 minutes, where I was asked a couple of coding questions along with some behavioral questions.

After the phone screen, I scheduled an onsite interview with multiple rounds including system design, problem-solving, and behavioral interviews. Overall, the experience was quite engaging, and the interviewers were supportive throughout the process. There was no strenuous pressure, but I was expected to explain my thought process clearly and effectively.

Technical Questions

  1. Given a binary tree, write a function to check whether it is height-balanced. (LC-110)
  2. Implement a function to perform a depth-first search traversal on a graph. (LC-104)
  3. Maximum Depth of Binary Tree (Tree, DFS)

Tips & Insights

For preparation, I focused on data structures, algorithms, and systems design principles as recommended for the role.
