Why Skill Evaluation Matters
Power BI is more than drag-and-drop dashboards. Success with Power BI relies on a solid grasp of data structuring, business context, and logical thinking.
Poor hiring decisions can lead to broken reports, unreliable data, or worse—misinformed decisions.
Here’s how to avoid that risk.
10 Must-Have Skills to Look for in a Power BI Developer
1. Hands-On Power BI Experience
A real expert doesn’t just “know” Power BI—they’ve built and deployed dashboards across departments. Ask them to explain a project they’ve worked on end-to-end. Evaluate how they handled data connections, report layout, and performance tuning.
2. Understanding of the Microsoft BI Stack
Ensure the candidate is skilled in using Power Query, Power Pivot, SSAS, and understands how to connect Power BI with Azure-based solutions. A true Power BI professional knows how the BI stack works together, not just in isolation.
3. Strong Data Analytics Background
Power BI is a tool—but insights come from strong analytical thinking. Ask scenario-based questions: How would you identify a dip in revenue across product segments? This reveals their logical problem-solving ability.
4. Data Preparation and Cleaning Skills
Dirty data is a daily challenge. A skilled developer should know how to use Power Query Editor for transforming, merging, and shaping datasets. They should demonstrate proficiency in building ETL pipelines and maintaining clean, reliable data sources.
5. Experience in Data-Specific Roles
Candidates with past roles like Data Analyst, BI Developer, or Data Engineer bring valuable perspective. Their history reflects practical data storytelling, domain understanding, and metric design.
6. Data Modeling Expertise
A strong foundation in data modeling is essential—this includes building star schemas, managing relationships, and creating calculated tables.
. Ask them how they optimize data models for performance or design relationships between multiple sources.
7. Mastery in DAX and SQL
DAX is the heart of Power BI’s intelligence. From calculated columns to time intelligence, test their DAX logic. They should also be able to write and understand SQL queries to validate and retrieve data from the source effectively.
8. Visualization & Storytelling
Remember, it’s not just about building visually appealing dashboards—it’s about delivering insightful and accurate data stories that drive decisions.
. Ask: How do you decide which visual to use for what data? or How do you make your dashboards user-friendly?
9. Soft Skills: Communication & Creativity
A good Power BI developer communicates well with business teams. They should be able to simplify data for non-technical users and translate requirements into solutions. Creativity helps them build intuitive dashboards with minimal instructions.
10. Attention to Detail and Problem Solving
Great dashboards need pixel-perfect attention. Even a small mistake in logic or data alignment can lead to incorrect decisions. Test this with a practical challenge or by reviewing their past work.
Bonus: Key Supporting Skills to Look For
- Python or R for Advanced Analytics
- Familiarity with Analytical Languages
- Software Development Principles (version control, agile workflows)
- Business Intelligence Fundamentals (KPIs, data warehousing concepts)
