Keep Metrics Consistent Across Reports

Context

You are comparing the same financial metric across multiple reports and time periods, and the numbers do not always match. Small differences in filters, date boundaries, or aggregation logic can create inconsistent results.

Core question

Explain how you would make sure your analysis stays consistent across different reports or time periods. In your answer, describe how you would standardize date handling, align filters and definitions, and verify that totals reconcile when the same metric is rebuilt in more than one query.

Scope guidance

Focus on practical SQL and data-manipulation habits you would use to prevent mismatched results, not on dashboard design. You should cover how to compare outputs, isolate differences, and use repeatable logic so the same metric returns the same answer everywhere it is used.
