About the test

The DAX online test assesses candidates' ability to use DAX for Power BI reports. 

It’s an ideal test for pre-employment screening. A good Power BI developer needs to be able to write DAX expressions, to create calculated columns, measures, and custom tables from data that is already in your model.

This online test requires candidates to answer multiple-choice and fill the blanks questions about DAX.
