Candidates who reference “natural language queries,” “real-time reporting,” or “Excel integration” show deeper knowledge of business intelligence tools.
What are some drawbacks or limitations of using Power BI?
While Power BI is a powerful data visualization tool, it comes with certain limitations that hiring managers and data professionals should be aware of:
- File size limits: Power BI does not support files larger than 1 GB for imported data. This can be a bottleneck when working with large datasets.
- Limited real-time data connections: Very few data sources support real-time connections within Power BI. If your company relies on real-time updates, this can be a challenge.
- Data integration restrictions: Power BI does not allow mixing imported data with data accessed through direct real-time connections in the same model.
- Sharing constraints: You can only share dashboards and reports with users who are signed in using the same email domain. This limits external collaboration or sharing outside your organization.
- Dashboard parameter limitations: Dashboards cannot pass or accept user-specific, account-specific, or entity-specific parameters, making it harder to tailor content dynamically per user.
Comment:
When screening candidates for Power BI roles, it's a smart move to ask about these limitations. Candidates who can identify and offer workarounds or best practices show a deeper knowledge of the platform. For example, if they mention optimizing data before loading, managing datasets in workspaces, or using parameters to simulate dynamic content—these are signs of real-world experience.
What are some differences in data modeling between Power BI Desktop and Power Pivot for Excel?
When screening candidates for roles involving data analytics or business intelligence, understanding their grasp of data modeling in different tools is essential. A solid interview question is:
"What are some differences in data modeling between Power BI Desktop and Power Pivot for Excel?"
This question helps assess the candidate's technical understanding and experience with these platforms. You're looking for someone who can compare features and explain how they’d approach a data modeling problem using either tool.
Comment:
A strong candidate should highlight key technical differences. For example:
- Power Pivot for Excel supports only single-directional relationships (one-to-many).
- It allows for calculated columns, but lacks more advanced model components like calculated tables.
- Import options in Power Pivot are limited — typically just a single import mode.
In contrast, Power BI Desktop provides:
- Bi-directional cross-filtering relationships, which offer more flexible data interaction.
- Features like calculated tables, row-level security, and multiple import modes (DirectQuery, Import, or Dual).
- More advanced modeling and DAX capability—especially useful for building interactive, dynamic dashboards.
Best practice: Look for candidates who not only mention the technical differences but also explain when and why one tool might be used over the other depending on the project size, collaboration needs, or data complexity.
Name the different connectivity modes available in Power BI?
Power BI provides three main connectivity modes for connecting to data sources:
- Import Mode: This is the default and most commonly used mode. Data is imported into Power BI Desktop and stored in the in-memory model. It's fast and supports advanced features like relationships and calculated measures.
- DirectQuery Mode: This mode connects directly to the data source without importing the data. Power BI stores only metadata, and queries are sent to the data source in real-time. It works well with large datasets where import is not practical.
- Live Connection: Similar to DirectQuery, but it only works with specific Microsoft services like SQL Server Analysis Services (SSAS). No data is stored in Power BI; instead, it connects live to the cube model.
Comment:
Understanding these three connectivity modes is essential when screening candidates for Power BI roles. Ask the candidate to explain each mode with examples. A strong candidate should not only name them but also elaborate on when and why to use each mode. Best practice is to prefer Import Mode for performance unless real-time access is required—then DirectQuery or Live Connection may be more appropriate. Look for candidates who can explain the trade-offs clearly.
What are the various types of refresh options provided in Power BI?
When evaluating a candidate for a role that involves Power BI, it's important to assess their understanding of the different refresh options available. A strong candidate should clearly explain the following four refresh types:
- Package Refresh: This syncs the Power BI service with changes made in the original file (like a Power BI Desktop or Excel file) stored in OneDrive or SharePoint Online. It doesn’t pull new data from the data source, just updates the file itself.
- Model (or Data) Refresh: This is the most common refresh, pulling updated data directly from the source into the Power BI dataset. It ensures reports and visuals reflect the latest data.
- Tile Refresh: Power BI tiles, like dashboards, are refreshed every 15 minutes by default. A tile refresh updates the cache for tiles to display the latest visuals.
- Visual Container Refresh (also called Report Visual Refresh): This happens when a user opens a report or interacts with it. The visuals refresh to reflect current cache or data.
Comment:
Look for candidates who not only know the four types but understand which refresh to use in different scenarios. Best practice: the right refresh type maintains performance and ensures up-to-date insights. If they can confidently describe real-world use cases for each, that's a great sign they’ve worked actively with Power BI.
What types of data sources can Power BI connect to?
This question helps you assess the depth of a candidate's technical knowledge and hands-on experience with Power BI integrations. A strong answer should include a variety of data sources and show that the candidate understands Power BI’s flexibility in working with both cloud-based and on-premises data.
Best practice: Look for candidates who can not only list these sources but also explain use cases or limitations.
Power BI can connect to a wide range of data sources, including:
- Files: Excel, CSV, XML, JSON, PDF, SharePoint Folder
- Databases: SQL Server, MySQL, Oracle, PostgreSQL, IBM DB2, Amazon Redshift
- Power Platform: Power BI Datasets, Power BI Dataflows, Dataverse
- Azure Services: Azure SQL Database, Azure Synapse Analytics, Azure Blob Storage, Azure Data Lake
- Online Services: SharePoint Online, Dynamics 365, Salesforce, Google Analytics, Microsoft Exchange Online
A well-rounded response should reflect familiarity with these categories and demonstrate practical experience using them in real projects.
What is a dashboard in Power BI?
A dashboard in Power BI is a single-layer presentation sheet that displays multiple data visualizations in one place. It offers key insights at a glance and allows users to interact with tiles linked to reports for deeper analysis. Dashboards are ideal for monitoring business metrics in real time and can be shared with others for collaborative decision-making.
Comment:
A dashboard is a single-layer presentation sheet of multiple visualizations reports. It allows you to drill through the page, bookmarks, and selection pane and also lets you create various tiles and integrate URLs. A dashboard can also help you set report layout to mobile view.
When screening candidates, look for responses that mention:
- Real-time data monitoring
- Visual elements like charts, KPIs, and graphs
- Interactivity features (like clickable tiles or drill-throughs)
- Mobile-friendly reporting
- Integration and sharing capabilities in Power BI
Best practice tip: A strong candidate should understand how dashboards differ from reports — dashboards are summaries for quick insights; reports offer detailed data. Look for clarity in how they explain this difference.
How do you define relationships in Power BI Desktop?
In Power BI Desktop, relationships between tables are defined in two main ways:
- Automatically: When you import multiple tables and the “Auto-detect relationships” setting is enabled, Power BI will try to detect and create relationships based on similar column names and data types (like a primary key in one table and a foreign key in another). This is helpful but not always perfect—always double-check the results.
- Manually: You can create relationships yourself by going into Model View, selecting the related columns, and specifying the relationship type (one-to-many, many-to-one, etc.). This ensures more accuracy, especially when Power BI can’t write the logic correctly on its own.
Comment:
Understanding relationships is key to building robust data models in Power BI. During screening, look for candidates who know how and when to use both manual and automatic relationships. A good answer should mention using Model View, understanding cardinality (one-to-one, one-to-many), and why it's important for interactive dashboards and visual accuracy. Best practice is to validate or adjust auto-detected relationships manually to avoid future data issues.
Can you have more than one functional relationship between two tables in a Power Pivot data model?
No. While it's possible to create multiple relationships between two tables in a Power Pivot data model, only one can be active at a time.
The active relationship is the one used by default in calculations, visualizations, and pivot tables. It's shown as a solid line in the data model view. The others, known as inactive relationships, are shown as dotted lines and can only be used deliberately in DAX formulas using the `USERELATIONSHIP` function.
Why this matters when interviewing:
This question helps assess a candidate’s real-world experience with data modeling. Many candidates might know how to connect tables but may not understand the impact of multiple relationships on data accuracy and reporting logic.
Follow-up tip: Ask how they would handle a scenario that requires switching between relationships in a report. A strong candidate will mention using DAX and managing relationships carefully to avoid confusion.
Best practice: Look for answers that explain the need for accuracy in choosing the right relationship and using functions like `USERELATIONSHIP` — these show practical knowledge, not just theory.
Can you have a table in the model which does not have any relationship with other tables?
Yes, you can. In a data model, it's possible to have a standalone table with no direct relationships to other tables.
This usually happens for two main reasons:
- To support slicers or dropdown filters in reports. These tables are often used to present parameter values or categories the end user can select to control visuals or calculations without affecting the model's relationships.
- As a placeholder for metrics or visual control. Sometimes, tables are added just to store predefined metrics, segments, or calculation flags that help guide the user interface without needing connections to the fact or dimension tables.
Best practice tip: When using unlinked tables, make sure their purpose is clear within the report. Clearly label them and ensure that their interaction via DAX measures or slicers is intentional and tested.
What is the CALCULATE function in DAX?
The CALCULATE function in DAX is one of the most powerful tools in Power BI and data analysis. It evaluates an expression — like a sum or a count — but lets you apply custom filters while doing it. This means you can shift the filter context to control exactly how and when your data is calculated.
A common use case: calculating total sales only for a particular region or time period. For example:
CALCULATE(SUM(Sales[SalesAmount]), Region[RegionName] = "North")This formula sums up sales, but only where the region is "North".
---
Why it matters in candidate screening:
Use this question to evaluate a candidate's real-world understanding of DAX. You're not just looking for the textbook definition — you want to hear how they've used CALCULATE in actual reports or business situations. The best responses explain:
- Why CALCULATE is essential
- How it changes filter context
- Example scenarios, like dynamic reporting or time intelligence
Best practice tip: Favor candidates who can explain CALCULATE with simple language and real examples. It shows they actually know how to apply DAX in practice, not just memorize syntax.
Where is data stored in Power BI?
Power BI stores data in several ways depending on how it's being used. Most commonly, data is stored in the cloud using Microsoft Azure. This includes services like Azure SQL Database and Azure Blob Storage, which provide secure and scalable solutions for storing large datasets.
When using Power BI Desktop, the data is stored locally in a compressed format within the `.pbix` file. This allows for offline work and previewing reports before publishing. Once the dashboard is published to the Power BI Service, the data typically transitions to Microsoft's cloud environment.
For enterprise-level use, Power BI can also connect directly to on-premises databases or real-time data via DirectQuery, meaning the data stays in its original location but is accessed live.
Comment:
This question helps you check if a candidate understands how Power BI works behind the scenes. An ideal response should mention Azure and highlight that Power BI stores data both locally (in pbix files) and in the cloud. It’s a good way to test their grasp of data flow and storage in business intelligence tools. Look for clarity on cloud storage (especially Azure), and whether they understand the difference between import and live query modes.
What is row-level security?
Row-level security (RLS) is a data access control feature that restricts data in a database based on the characteristics of the user running a query. In simpler terms, it limits what data a user can see, depending on rules defined for their role.
In tools like Power BI, RLS works by setting up filters on tables in Power BI Desktop. These filters control data access at the row level for different users, ensuring that each user can only view data that's relevant to them. Once published to Power BI Service, these roles and rules continue to apply, offering a secure, customizable data sharing experience.
Comment:
This question helps you assess whether the candidate understands data security at a granular level. A good answer should include the idea of filtering data based on user roles and mention Power BI Desktop and Power BI Service if applicable. Look for candidates who can explain both the concept and how it’s applied in real tools—that's the best-practice approach.
Why should you apply general formatting to Power BI data?
Applying general formatting to your Power BI data helps Power BI understand the type, structure, and significance of your data more easily. This enhances how the tool interprets, processes, and displays information in reports and dashboards.
Comment:
Using general formatting makes it easier for Power BI to categorize and identify data. It helps ensure consistency and improves how data is sorted, filtered, and visualized. A best practice is to apply formatting standards early in your data preparation process so you don’t run into confusion later. Hiring managers can use this as a quick check to see if candidates understand the importance of clean, structured data when building reports.
What are the different views available in Power BI Desktop?
Power BI Desktop offers three main views that help users work with data and create insights:
- Report View – This is where you build your dashboards and reports. You can add visualizations, interactive charts, filters, and even create multiple report pages. It's ideal for presenting data in a visual and easy-to-understand way.
- Data View – This shows the underlying data in a spreadsheet-like format. It's useful for checking data quality, making small edits, and shaping the data using the Query Editor tools.
- Model View – This view helps you manage relationships between tables. If you're working with complex datasets, this is where you define relationships and set up your data model.
Comment:
There are three different views: Report View (add visualizations and additional report pages), Data View (data shaping using Query Editor tools), and Model View (manage relationships between complex datasets). When screening candidates for Power BI roles, listen for clear, confident explanations of all three. Best practice questions can include asking how they've used each view in past projects to see if they understand the practical use and not just the theory.
What are the various versions of Power BI?
When screening candidates for Power BI roles, asking this question helps evaluate their understanding of the tool’s ecosystem. It's a basic yet essential question, especially for roles where reporting and data visualization are key.
The main versions of Power BI include:
- Power BI Desktop: A free application installed on a computer for creating reports and data models. Most used by developers and analysts.
- Power BI Service: A cloud-based platform to publish, share, and collaborate on reports. Ideal for business users and decision-makers.
- Power BI Mobile Apps: Available for both iOS and Android, these let users view and interact with dashboards on the go.
Best practice approach: Look for candidates who not only name the versions but also explain when and why each version is used. This shows real-world experience and not just memorization. If a candidate mentions Power BI Report Server, give points for depth — it’s used for on-premise solutions.
Explain the building blocks of Microsoft Power BI
Asking a candidate to explain the building blocks of Microsoft Power BI is a great way to assess their technical knowledge and practical experience with data analytics tools. This question helps identify if they understand how Power BI works from the ground up and can use it in a real-world business context.

Real-World Success Stories with Power BI Interview Questions
When it comes to screening candidates effectively, several industry leaders have paved the way with proven approaches to power bi interview questions.
Gartner's Magic Quadrant consistently ranks Microsoft Power BI as one of today's top business intelligence tools. This recognition isn't just academic - it reflects how most IT firms now rely on Power BI for their critical business analytics needs. This widespread adoption means recruiters are seeing more candidates with Power BI skills, making proper screening even more crucial.
Leila Gharani, a 7-time Microsoft MVP with over 20 years of experience, has helped thousands of professionals master Power BI. Her comprehensive course has attracted 12,812 students, demonstrating the massive demand for Power BI expertise in the job market. Gharani's approach emphasizes practical, real-world applications - exactly what hiring managers should focus on during interviews.
Edureka's Power BI certification program takes screening seriously too. Their course is certified by PwC Academy and features industry experts with over 10 years of hands-on experience. The curriculum covers Power BI Desktop, DAX, Service, Data Transformation, and Reports - all key areas that should appear in your power bi interview questions.
The Power BI Guy (Raja Usman Ayub) has built a YouTube following of 23K subscribers by focusing on practical interview preparation. His comprehensive video tutorial covering 50 Power BI interview questions serves both beginners and experienced professionals, showing there's real demand for structured interview approaches.
Why Video Screening is Revolutionizing Power BI Recruitment
The recruitment landscape is shifting dramatically toward video screening software, and for good reason. Traditional phone screens and in-person interviews often fall short when evaluating technical skills like Power BI proficiency.
Video screening allows candidates to demonstrate their Power BI knowledge rather than just talk about it. They can share their screen, walk through dashboards, and explain their thought process in real-time. This gives recruiters much deeper insights into a candidate's actual capabilities.
Time efficiency is another major factor. Instead of scheduling multiple rounds of interviews, recruiters can review video responses on their own timeline. This speeds up the entire hiring process while maintaining quality assessments.
The consistency factor can't be overlooked either. Every candidate gets asked the exact same power bi interview questions in the same format, eliminating interviewer bias and ensuring fair comparisons.
Remote work trends have also accelerated video screening adoption. With distributed teams becoming the norm, video-first recruitment processes feel natural and comfortable for both candidates and hiring managers.
