About the test

The Power BI online test assesses knowledge of creating reports using Power BI.

The assessment includes work-sample tasks such as:

  • Using DAX to create reports.
  • Transforming and preparing data with Power Queries.
  • Configuring charts to summarize and visualize data.

A good Power BI developer needs to know how to correctly configure charts and use Power Query to clean the data, as well as use DAX to create advanced reports.

Quick Measures

As an entry-level financial analyst, your manager asked you to analyze the prices of a new stock and make a buy-sell recommendation. Daily price trends seems to fluctuate as can be seen below:

Trendline for prices.

You need to create a new measure which will create a rolling average for 7-day periods, as below, because an increasing trend in a rolling average may signal an increase in the price of the stock.

Decorative quote

Simple, straight-forward technical testing

TestDome is simple, provides a reasonable (though not extensive) battery of tests to choose from, and doesn't take the candidate an inordinate amount of time. It also simulates working pressure with the time limits.
