Your question is Validating Executive SQL Reports. 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).

Problem

Context

Leadership reports often drive decisions, so a small SQL mistake can create a large business problem. Interviewers ask this to see whether you have a disciplined process for validating query outputs, not just writing queries.

Question

Explain the steps you take to verify the accuracy of a report before presenting it to leadership. In your answer, cover how you validate source data, confirm business logic, test filters and aggregations, and check for edge cases such as nulls, duplicates, or missing records.

Scope Guidance

Keep the answer practical and SQL-focused. The interviewer expects a structured validation approach: how you compare results to known baselines, how you sanity-check totals and row counts, and how you make sure the final output matches the metric definition and reporting period.
