Interview Process

The first round was a combination of coding and behavioral questions. I began with some basic behavioral questions about my background and motivations, discussing my projects and what I learned from them.

We then moved on to technical questions. The first question involved implementing a binary search algorithm from scratch, explaining its time complexity, and discussing how it differs from linear search. The interviewer provided feedback as I coded, and we discussed potential edge cases.

The second question focused on tree traversal, where I had to find the maximum depth of a binary tree. I explained my approach using breadth-first search and also touched on depth-first search strategies, clarifying the nuances of my solution and how I would implement it in a production setting.

Overall, the interview process was interactive, and the interviewer was engaging, providing hints when I seemed stuck. A good understanding of the basics and the ability to communicate my thought process were crucial to my success.
