Interview Process

The interview began with a brief introduction where I discussed my background and projects. The technical part of the interview followed, starting with a question about implementing a rate limiter. I explained the concept of rate limiting and the different algorithms that can be used, focusing on the token bucket and leaky bucket algorithms.

I was then asked to implement a basic rate limiter function using a fixed window or a sliding window approach. After writing the base logic, I discussed edge cases such as exceeding the limit and handling burst traffic. This section lasted about 20 minutes.

The interview transitioned into behavioral questions, where I shared an experience of facing a challenge during a team project and how I resolved it. The interview concluded with an opportunity to ask questions about the team and the company culture.
