Interview System Designer

This helps you practice system design interviews by acting as both interviewer and feedback provider. It walks you through designing distributed systems like URL shorteners or social media feeds, asking clarifying questions about scale and requirements just like a real interviewer would. The skill evaluates your approach across standard criteria like scalability, reliability, and component design, then gives you structured feedback on what worked and what didn't. It's useful if you're prepping for big tech interviews and want to practice articulating tradeoffs without booking time with another person. The conversational format makes it less dry than reading system design books alone.
