Interview Process
The interview process consisted of a technical phone screen focused on system design and problem-solving skills. The main question was about implementing a rate limiter. The interviewer asked how to handle high request rates efficiently, discussing different strategies such as token bucket and leaky bucket algorithms.
I provided an overview of the token bucket algorithm, explaining how it works by allowing a fixed number of requests per unit time while allowing bursts of traffic up to a certain limit. The interviewer followed up by asking for potential edge cases and how to handle them, such as what to do when the token bucket runs out.
Next, we discussed scalability and how to measure performance under load. I suggested using a queue to manage incoming requests and ensuring that the system can scale horizontally by adding more nodes as traffic increases. Overall, the conversation was engaging, and the interviewer was very knowledgeable.
