Interview Guides
In analyst work, the chart choice is often determined by the shape of the SQL result set and the question a stakeholder needs answered. A strong answer should connect the data transformation in SQL to the visualization shown in a Tesla dashboard or review.
Explain how you decide between visualization types when presenting insights to stakeholders. Use SQL-oriented examples to compare when you would use a bar chart versus a scatter plot, and also discuss how grouped aggregates, time-based trends, categorical breakdowns, and outlier detection influence your choice. You should describe how you would structure the underlying query and what result shape each chart expects.
Keep the discussion practical rather than purely design-focused. The interviewer is looking for a clear framework that ties stakeholder questions, SQL transformations, and chart selection together, including trade-offs and common mistakes.
