Ensuring Regulatory Data Accuracy

Context

Regulatory reporting requires complete, accurate, and auditable data. Interviewers ask this question to assess whether you can use SQL and data controls to prevent incorrect submissions.

Question

Explain how you ensure the accuracy of data submitted to regulatory bodies. Your answer should cover:

1. How you validate source data before reporting
2. How you use SQL checks such as filtering, aggregation, and reconciliation
3. How you detect missing, duplicate, or inconsistent records
4. How you create an audit trail and handle corrections

Scope Guidance

Keep the answer practical and structured. The interviewer is not looking for advanced theory; they want a clear process for using SQL and data quality controls to verify reporting datasets before submission, plus how you would document and monitor the process over time.
