16 Power BI Interview Questions with Answers for you

1. How do you improve the performance of a Power BI report?
Optimize data models, use aggregations, limit visuals on a report page, apply filters to reduce data load, and enable query folding.

2. What type of data sources did you use in your previous project?
Depending on the project requirements, common sources include SQL Server, Azure, Excel, and APIs.

3. What is the difference between Star Schema and Snowflake Schema?
A Star Schema has a central fact table connected to dimension tables, while Snowflake Schema normalizes dimension tables into sub-tables.

4. What is the CALCULATED function in Power BI?
CALCULATED modifies the context of a calculation and returns the result based on the new filters.

5. Tell me about complex DAX functions you used.
I have used functions like CALCULATE, FILTER, and RANKX to create complex calculations for performance metrics.

6. How do you install the Data Gateway in Power BI?
Download the Gateway from Power BI service, install it, and configure it with the on-premises data source.

7. What is the difference between Data Query and Data Flow?
Data Query refers to queries in Power Query Editor, while Data Flow is used to transform and reuse data in multiple datasets.

8. What is the difference between Calculated Columns and Measures?
Calculated columns are static and stored in the model, while measures are dynamic and calculated during report interaction.

9. What is Query Folding in Power BI?
A: Query folding optimizes queries by delegating transformations back to the data source to improve performance.

10. What is the difference between RANK and DENSE RANK in SQL?
A: RANK skips numbers for ties, whereas DENSE RANK assigns consecutive ranks even with ties.

11. What are the types of Context in Power BI?
There are three types: Row Context, Filter Context, and Query Context, used to manage how data is filtered and displayed.

12. Give an example of INNER JOIN in SQL.
SELECT * FROM Orders o INNER JOIN Customers c ON o.CustomerID = c.CustomerID;
returns rows where the condition is met.

13. What is the difference between Filter and Slicer in Power BI?
Filters are applied in the backend, while slicers are visual controls for users to filter data interactively on the report.

14. What are the fundamentals of Power BI?
Power BI fundamentals include data modeling, DAX calculations, data visualization, and report sharing through the Power BI Service.

15. What is Row Level Security in Power BI?
It defines rules to control which data users can view in Power BI reports, based on their roles.

16. What are the different types of subscriptions in Power BI Report Server?
Subscriptions include email-based report delivery, SharePoint delivery, and Power BI Service for scheduled data refresh.
