Your question is Designing a Real-Time Market System. 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).
Explain how you would design a real-time market system, including data ingestion, latency, and reliability considerations. Clarify whether “market” means a financial market, a marketplace, or another domain, and identify the system’s users and critical workflows. Cover the end-to-end architecture, online and offline processing, latency and availability objectives, observability, failure recovery, and any ML components such as detection, prediction, retrieval, or ranking.
