Your question is Troubleshooting Production Data Quality. 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).
Describe a time you had to troubleshoot a data quality issue in production.
Explain how you detected and scoped the issue, determined its root cause, prioritized the response, and communicated with affected stakeholders. Cover the technical actions you took, how you handled uncertainty or competing priorities, and what you changed to prevent recurrence. Be specific about your individual ownership and the measurable outcome. A strong response should use a clear STAR structure, distinguish symptoms from root cause, and include both immediate remediation and a lasting process, monitoring, or testing improvement.
