Your question is Test Planning for ETL Data Formats. 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).
What test planning would you do for an ETL project where data must be entered in different formats?
Explain how you would organize test coverage, environments, test data, validation checkpoints, automation, defect triage, and release readiness. Address format conversion, malformed inputs, schema changes, data quality, reconciliation, and downstream impact. Prioritize the work and explain how you would coordinate dependencies with engineering, data owners, and business stakeholders.
