Your question is Data Quality in Batch Pipelines. 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 do you ensure data quality and handle failures in a batch pipeline?
Focus on practical controls for validation, retries, idempotency, and backfills. Explain how you would detect bad records, prevent duplicate loads, and recover from partial job failures without corrupting downstream tables.
