Welcome to your interview.
The question is on your right: Diagnose Dashboard Pipeline Failures. 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.
You are supporting a business dashboard used by analysts and operations teams. A chart is showing unexpected values, but the same report looks correct for some users and wrong for others. You need to isolate where the problem starts before the team spends time fixing the wrong layer.
What is your process for identifying whether a dashboard issue is caused by the data source, the workbook, or Tableau Server?
