Your question is SQL for BI Reporting. 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).

Problem

Context

Many analytics and business intelligence roles rely on SQL even when dashboards are built in tools like Tableau, Power BI, or Looker. Interviewers ask this question to understand whether you can connect raw data to decision-ready reporting.

Core question

Describe your experience using SQL alongside data analytics or BI tools. Explain how you used SQL to prepare data, validate metrics, and support dashboards or recurring reports. Discuss the types of queries you wrote, such as filtering, aggregations, grouping, and basic data cleanup.

Scope guidance

Keep your answer practical rather than theoretical. The interviewer is usually looking for evidence that you can use SQL to answer business questions, create reliable datasets for reporting, and work effectively with analysts or dashboarding tools. Mention the kinds of metrics you analyzed, how you ensured accuracy, and how SQL fit into your broader analytics workflow.
