Hire Power BI developers in 2024

Microsoft Power BI is a business intelligence platform that provides non-technical professionals with tools to compile, analyze, visualize, and share data. Its goal is to connect data sources, allowing companies to find insights in their own data.

According to Microsoft it encompasses “a collection of software services, applications, and connectors that work together to transform…unrelated data sources into coherent, visually immersive, and interactive insights.”

Data can come from Excel spreadsheets or on-premises or cloud data warehouses and can be transformed into reports, tables or graphs. Power BI includes the following components:

• Power BI Desktop a Windows desktop application
• Power BI service an online software-as-a-service (SaaS) application
• Power BI mobile apps for all major mobile operating systems
• Power BI report builder that allows users to create reports to share
• Power BI report server that provides a place to publish Power BI reports

The platform can be used for various purposes across all professional responsibilities. For example, a sales professional might use it to track sales numbers, while a marketing professional might use it to better understand customer engagement data. Meanwhile, an executive can use it to examine what-if scenarios. Developers can deploy it to create custom applications.

In this article you will learn, among other things, how to hire Power BI developers .

Power BI administrator and specialist

Data analysis has become mandatory for companies that want to compete. While Power BI can be used by most professionals, companies may still want someone on staff who can provide additional analytical skills. A Power BI developer is that person — someone who has a deep understanding of the application and can help colleagues convert data into meaningful business insights.

Those in this position can take on a variety of roles depending on the company's requirements. For example, the Power BI developer might maintain the Power BI tool, design and develop reports, or use Power BI to extract insights and provide recommendations. Power BI developers must have high knowledge of the platform and also have experience in business intelligence and databases.

Interview Questions

The following questions are just a few that employers can use to assess the skill level of potential Power BI developers.

What is a panel?

A dashboard is a single visualization that includes multiple elements to help viewers visualize complex information quickly. It provides high-level views that users can select for more information on specific topics. These high-level elements are called blocks and can be pinned or moved to create a more useful visual interface.

What is DAX?

DAX is a data analysis expression, which is a library of formulas used for calculations and data analysis. Includes functions, constants and operators. DAX formulas can be numeric or non-numeric and always begin with an equals sign (=).

What are the differences between Power BI and Tableau?

Power BI uses DAX to calculate table columns, while Tableau uses multidimensional expressions (MDX). Additionally, Tableau can handle more data than Power BI. And Tableau is harder to learn than Power BI.

How does Power BI work?

Power BI mainly operates in 3 steps: data integration, data processing and data presentation. Data integration involves compiling data from multiple sources and converting it to a standard format. Data processing involves “cleaning” data to make it usable for analysis. Data presentation involves displaying data in a way that is easy for users to understand, such as reports, dashboards, and graphs.
