Interview Process
The interview consisted of a technical phone screen focused on a rate limiter question. The interviewer explained the requirements for a rate limiter that allows a specific number of requests per time period. I discussed basic algorithms like token bucket and leaky bucket to manage request flow. I implemented the rate limiter in Python, walking through the implementation step-by-step, discussing the data structures used and how to handle edge cases like burst traffic. After completing the code, we explored theoretical scenarios to test the implementation, including multi-threading aspects and performance considerations. Overall, it was a challenging yet insightful experience.
