Interview Process

The interview process was structured into two primary segments: coding problems and behavioral questions. The coding segment primarily focused on data structures and algorithms, with common themes including tree manipulation and dynamic programming. I was asked to solve a problem where I needed to implement a binary tree traversal algorithm efficiently. After coding, the interviewer asked some questions related to time complexity and space optimizations.

The behavioral section involved questions aimed at assessing my past experiences and teamwork. For example, I was asked to discuss a time I faced a significant challenge in a project and how I overcame it. Overall, the interview was a combination of technical challenges and personal insights.

Technical Questions

  1. Binary Tree Traversal (Tree, Depth-First Search)
  2. Dynamic Programming - Coin Change (Dynamic Programming, Greedy)

Tips & Insights

Be prepared to explain your thought process during coding challenges and be ready to discuss your past experiences in detail, especially in terms of problem-solving and teamwork.
