System Design
Zoom
Prepare for Zoom’s System Design Mock Interview. Design a scalable video conferencing platform with real-time audio/video streaming, meeting coordination, and user management.
Interview Details

Step into a high-impact interview experience where you'll design a scalable video conferencing platform inspired by Zoom. You'll be challenged to architect a system that supports real-time audio/video streaming, seamless meeting coordination, and robust user management just like in a real-world FAANG+ interview. The session is structured to simulate the pressure and depth of an actual system design interview, with a mix of probing questions and requests for visual diagrams to test your communication and technical skills.

Throughout the interview, you'll clarify requirements, sketch out high-level and detailed architectures, and justify your design decisions. Expect to be pushed with curveball questions and follow-ups that probe your depth of knowledge, adaptability, and ability to handle ambiguity—mirroring the expectations of top-tier tech companies.

Get ready to:

  • Practice breaking down complex requirements and defining system scope.
  • Design scalable, low-latency architectures for real-time communication.
  • Justify technology choices for APIs, databases, and media streaming.
  • Tackle trade-offs in scalability, consistency, and availability.
  • Communicate your ideas clearly with diagrams and structured explanations.

By the end, you'll be better equipped to approach system design interviews with confidence, ready to tackle challenging scenarios and articulate your solutions like a seasoned engineer.
