Discord 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 Discord, focusing on real-time text, voice, and video communication, message persistence, and scalability. The interview simulates a real System Design round, challenging you to define, design, and discuss how to build a high-performance, globally distributed communication platform. Expect a blend of conceptual reasoning, deep technical exploration, and scenario-based challenges.

What You'll Practice:

• Structuring and communicating end-to-end system architectures clearly.
• Designing for low latency, scalability, and high availability in real-time systems.
• Applying System Design principles to messaging, streaming, and synchronization workflows.
• Creating clear, well-organized design diagrams that capture key components and data flow.
• Thinking critically about trade-offs between performance, consistency, and reliability under interview pressure.

By the end of this System Design Mock Interview, you’ll be ready to tackle top-tier system design interviews with confidence and demonstrate strong architectural reasoning across large-scale, real-time communication systems.
