Your question is Structured Approach to Customer Issue Triage. 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).
When a customer reports a data issue, you often need to move quickly between application logs, SQL, and remote desktop tools such as Citrix or Microsoft Remote Desktop to isolate the cause.
Describe your process for handling that investigation end to end. Explain how you decide what to check first, how you use SQL to validate whether the problem is in the data or the application layer, and how you use remote desktop access safely and effectively when you need to reproduce the issue or confirm a fix.
Keep your answer practical and structured. The interviewer is looking for how you prioritize evidence, communicate findings, and avoid making the issue worse while you troubleshoot.
