Data Analyst

Practice Power BI interview questions with natural sample answers for BI analyst and data analyst roles. Work through DAX filter context, data-model grain, report reconciliation, refresh failures, row-level security, storage choices and performance. The scenarios include concrete examples and interviewer follow-ups so you can explain your decisions, not just name a feature. Start with the six complete free answers, then practice the deeper cases. Read each sample aloud, adapt it to your model and experience, and keep only claims you can support. Numerical examples are hypothetical test cases. Check product behavior and licensing against the linked Microsoft documentation for your environment. Eight senior, open-ended cases explore historical corrections, composite models, exact aggregations, Direct Lake consistency, aggregate confidentiality, certified metric changes, release decisions and export incidents. Practice a defensible recommendation, the alternatives and the evidence that would change your decision; there is no single model answer for these design choices. Each senior case includes a second-round pressure test that changes a constraint and asks you to revise your recommendation.

Read the example aloud, then adapt it to your own experience. Use details you can explain in a follow-up.

• How would you explain row context and filter context using a sales report?
• Why does a distinct-customer grand total differ from the sum of the regional rows?
• A report refreshes in Power BI Desktop but fails after publication. How would you investigate?
• A regional manager can see every region even though you configured row-level security. What would you check?
