Interview Process

During the phone interview, I was asked to solve the Robot Grid Distance Challenge, which involved determining the number of unique paths for a robot on a grid. The interviewer provided a brief explanation and asked if I was ready to proceed with coding.

I started by clarifying the problem statement and discussing the various approaches I could take. The interviewer appreciated my thought process and guided me through a few hints. I opted for a recursive approach first, then discussed how to improve it with dynamic programming to optimize for time complexity.

I wrote the code while explaining my thought process aloud. After successfully implementing the solution, the interviewer prompted me with a few edge cases to consider. We then had a discussion about the time complexity of my solution and possible improvements.

Overall, it was a challenging yet engaging experience, and I felt that I handled the technical questions and coding well. The interviewer was supportive and provided feedback throughout the process.
