System Design Question

How would you design a rate limiter for an API that handles 10,000 requests per second?

Candidate's spoken answer:

So basically you would use Redis for this because it's fast. You can store like a counter for each user and then increment it. And when it hits the limit you just return a 429. You could use a sliding window or something but honestly the token bucket is probably fine for most cases. The main thing is you want it to be distributed so Redis makes sense because it's in-memory and you know, it handles concurrent access pretty well.

    I used to freeze in system design rounds. After 2 weeks with Intabiu, I nailed the architecture discussion and got the offer.

    The filler word detection was a wake-up call. I didn't realize I said 'basically' in every answer.

    Frequently asked questions

    How is Intabiu different from LeetCode?
    LeetCode tests if you can solve problems. Intabiu tests if you can EXPLAIN your solutions. In real interviews, especially system design rounds, you need to communicate clearly under pressure. Intabiu is the only tool that trains this verbal skill with AI feedback.
    Why do I fail system design interviews even though I know the concepts?
    Most engineers fail system design interviews not because they don't know Kafka or Redis, but because they can't articulate WHY they chose one technology over another under pressure. Intabiu helps you identify communication blind spots before they cost you an offer.
    What is Intabiu?
    Intabiu is a voice-first interview simulator for software engineers. It trains you to explain, debate, and defend your technical decisions by speaking out loud. The AI analyzes your responses for clarity, logic gaps, filler words, and hesitation.
    What skills and topics does Intabiu cover?
    Intabiu covers 325+ skills including System Design, React, Python, AWS, Kubernetes, databases, microservices, and more. It also covers behavioral questions. Practice from junior to senior level questions in 20+ languages.
