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 approach error handling and logging within your data pipelines?
Discuss how you detect, classify, and recover from failures across ingestion, transformation, validation, and loading stages. Include retry policies, dead-letter handling, structured logs, alerting, data quality checks, and how you make failures traceable and safe to reprocess.
