ChatGPT System Design

Prepare for a System Design session led by an interviewer. Tackle ChatGPT functional requirements like user-interaction and real-time response handling focusing scalability and reliability.

Interview Details

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 ChatGPT, focusing on scalability, reliability, and real-time response handling. The interview simulates a real System Design round, challenging you to define, design, and discuss the architecture of a large-scale, high-performance conversational system. 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 scalability, performance, and fault tolerance.
  • Applying System Design principles to conversational AI and inference systems.
  • Creating clear, well-organized design diagrams that reflect key components and data flow.
  • Thinking critically about trade-offs in system design decisions 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 thinking.
