Your question is ETL Process You Built. 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).
Describe the ETL processes you have built.
Explain one representative pipeline end to end, including source systems, ingestion method, transformations, target storage, orchestration, data quality checks, failure recovery, and monitoring. Include the trade-offs behind your technology choices and how you handled incremental loads or backfills.
