How to Solve the System Design Question: "Real Time Chat Status Indicator"

​System design interviews can feel open-ended and overwhelming — but they don’t have to.

​In this live session, we’ll walk through how to approach a unique tech interview question: "Build a Real Time Chat Status Indicator".
You’ll discover how to break down requirements, identify trade-offs, and structure your solution like a senior engineer.

What you’ll learn:

• ​How to clarify requirements before jumping to solutions

• ​Core design decisions: scalability, availability, fault tolerance

• ​Trade-offs in system design — from core infrastructure (databases, caching, load balancing, queues) to communication models (polling, pub/sub, event-driven, realtime)

• ​How interviewers evaluate your thinking process
