Your question is Real-Time Multi-Source Analytics. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Design a system that ingests real-time data from multiple sources and makes it available for analytics.
Clarify source types, delivery guarantees, schemas, freshness, replay, ordering, security, and downstream analytics requirements. Explain the ingestion, validation, storage, serving, monitoring, and recovery architecture, including where ML could improve anomaly detection or data-quality management.
