Welcome to your interview.

The question is on your right: Validate Dashboard Metrics with SQL. Take a moment with it first.

Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.

Problem

Context

Dashboards in Swiss Re reporting surfaces are only useful if the underlying numbers can be trusted. For a QA Engineer, validating reported metrics usually means checking that the dashboard logic matches the source data and that edge cases are handled correctly.

Question

Explain how you would validate that a report or dashboard shows accurate data. Focus on how you would use SQL to reconcile dashboard totals back to source tables, verify grouped metrics, and test filters, nulls, duplicates, and date boundaries. You should also describe how you would investigate a mismatch between a dashboard number and a direct SQL result.

Scope guidance

Keep your answer practical and SQL-focused rather than discussing generic UI testing. The interviewer is looking for a simple, structured validation approach that a QA Engineer could use on Swiss Re reporting data.
