Interview Process

The phone screen started with a brief introduction of my background and motivations. I then transitioned into discussing my experience with rate limiting algorithms. The interviewer posed a question related to implementing a rate limiter using a sliding window algorithm. After explaining the concept, I was asked how I would handle edge cases, such as burst traffic. The conversation moved towards discussing system design principles, and I emphasized scalability and fault tolerance as key considerations. The interviewer appreciated my approach and prompted me to suggest improvements on existing solutions that I was aware of. After this technical section, I was also asked a few behavioral questions to understand my fit within the team. Overall, the interview lasted for about 30 minutes, and I felt that I connected well with the interviewer.
