Customer storytelling in a dashboard starts with the right SQL output. Before you build views in Tableau or DISH reporting surfaces, you need a clean dataset that highlights customer behavior, trends, and meaningful segments.
Explain how you would use PostgreSQL and a visualization tool such as Tableau to tell a customer story. Focus on how you would shape the SQL output first, what metrics or cuts you would include, and how you would structure the result so it works well in a dashboard. You should also describe how you would move from raw customer records to a simple narrative such as acquisition, engagement, decline, or churn risk.
Keep your answer practical and analyst-focused. The interviewer is looking for a clear explanation of dataset design, aggregations, filtering, and how SQL choices support the final visual story rather than a deep discussion of Tableau features alone.
