Your question is Real-Time Data Pipeline Design. 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).
How would you design a data pipeline to handle real-time ingestion from heterogeneous sources?
Discuss how you would ingest APIs, databases, files, and event streams; normalize differing schemas; support replay and late-arriving data; and deliver reliable downstream data. Explain your technology choices, orchestration model, data quality controls, monitoring, and failure recovery.
