LeetCode System Design

Prepare to dive into a System Design Mock Interview modeled after real interview rounds at FAANG+ companies and other leading tech firms. In this session, you’ll design the architecture of an advanced online coding and learning platform like LeetCode, focusing on scalability, performance optimization, and reliability. The interview simulates a real System Design round, guiding you through defining requirements, designing high-level and detailed architectures, and reasoning about trade-offs in large-scale system design. Expect to illustrate your ideas using diagrams and defend your choices through interactive discussion.

What You'll Practice:

• Structuring and communicating end-to-end system architectures clearly.
• Designing for scalability, performance, and fault tolerance in coding platforms.
• Applying System Design principles to online judge systems, problem management, and user submissions.
• Creating clear, well-organized design diagrams that capture key components and data flow.
• Thinking critically about trade-offs in database design, caching, and consistency models under interview pressure.

By the end of this System Design Mock Interview, you’ll be ready to confidently approach top-tier system design interviews, demonstrating your ability to build and articulate large-scale, performance-driven architectures.
