Your question is Describe Your ETL Process. 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 an ETL process that you developed.
Explain the source systems, ingestion method, transformations, target data model, orchestration, and how data quality was verified. Include the scale and service-level expectations you supported, the technologies used, how you handled failures and reruns, and how you monitored the pipeline. Be prepared to discuss one design trade-off, an incremental-loading or backfilling strategy, and how you would improve the process.
