In analyst work, two SQL reports often show different values for what appears to be the same metric because the underlying logic is not actually the same. This is common when one report is built for ASI ESP activity reporting and another is built for finance or account-level performance tracking.
Explain your process for reconciling two reports that use different definitions for the same metric. Walk through how you would compare the SQL logic, isolate differences in joins, filters, date handling, aggregation level, and CASE WHEN rules, and then prove which records are driving the mismatch.
Answer at a practical analyst level. The interviewer is looking for a structured reconciliation workflow, not just “I would check the queries.” You should show how you would use SQL to standardize definitions, build side-by-side comparisons, and communicate the final source of truth or documented reason for the variance.
