Company-Specific Interview Questions from Top MNCs

1. Can you explain what Power BI is and describe its key components?

Ans:

Power BI is a Microsoft business analytics tool that enables organizations to visualize and share insights. Its main components include Power BI Desktop for creating reports, Power BI Service for cloud-based sharing and collaboration, and Power BI Mobile for accessing reports on mobile devices, together delivering a seamless analytics experience.

2. How do you establish connections and load data from various sources into Power BI?

Ans:

Power BI allows connecting to multiple data sources like Excel, SQL databases, web APIs, and cloud services. Using the Get Data option in Power BI Desktop, users can connect to a source and either import data into the model or access it live, depending on the selected mode.

3. What is DAX and how does it differ from Power Query in Power BI?

Ans:

DAX (Data Analysis Expressions) is a formula language used for calculations and aggregations within Power BI. Power Query, on the other hand, is used before loading data to clean, transform, and shape it. Essentially, Power Query handles ETL tasks, while DAX performs analysis and calculations on the data model.

4. How do calculated columns differ from measures in Power BI?

Ans:

Calculated columns are added row by row and stored in the data model, usable in visuals or further calculations. Measures are dynamic calculations computed at query time, often aggregating data. Measures are generally more efficient for large datasets and interactive reporting.

5. What is row-level security (RLS) and how can it be implemented in Power BI?

Ans:

RLS (Row-Level Security) restricts data access so users see only what they are authorized to view. It is implemented by defining roles and applying table-level filters in Power BI Desktop, then assigning users to these roles via Power BI Service to enforce role-specific data access.

6. What methods are available to improve Power BI report performance?

Ans:

To enhance performance, reduce the data model by removing unnecessary columns and tables, simplify complex DAX formulas, use aggregations, limit visuals per page, and enable query folding in Power Query. These practices help reports load faster and run efficiently.

7. What types of filters does Power BI offer for report customization?

Ans:

Power BI provides several filter types: visual-level filters (single visual), page-level filters (entire page), and report-level filters (whole report). Slicers allow interactive selection of data subsets, giving users a dynamic way to filter report content.

8. What is the purpose of a Power BI Gateway?

Ans:

A Power BI Gateway connects cloud-based Power BI to on-premises data sources securely. It enables live or scheduled data refreshes without moving data to the cloud, ensuring dashboards and reports are always up-to-date.

9. How is data refresh managed within Power BI?

Ans:

Data refresh keeps datasets current by updating data from the source. Power BI Service allows scheduled refreshes, and gateways manage on-premises data updates. Full refresh reloads all data, while incremental refresh updates only new or modified records.

10. Can you explain the differences between Import, DirectQuery, and Live Connection modes in Power BI?

Ans:

Import mode loads data into Power BI for fast querying but requires periodic refresh. DirectQuery queries the source live for real-time data but may be slower. Live Connection connects directly to Analysis Services models, allowing live interaction without importing data.

1. What is Power BI and why is it important for business intelligence?

Ans:

Power BI is a Microsoft tool for data visualization and business analytics that transforms raw data into interactive dashboards and reports. It simplifies collecting data from multiple sources, analyzing it quickly, and sharing insights, helping businesses track trends, monitor performance, and make informed decisions. Its intuitive interface and integration with Microsoft tools make it a key asset for business intelligence.

2. How do you connect Power BI to different data sources?

Ans:

Power BI can connect to various sources such as databases, Excel files, cloud services, and web APIs. Using the Get Data feature in Power BI Desktop, users select the source, provide credentials, and establish the connection. Data can then be imported into Power BI or accessed live, offering flexibility for different analytical needs.

3. What is the difference between Power Query and DAX in Power BI?

Ans:

Power Query is used to extract, clean, and transform data before loading it into the model it’s the data preparation stage. DAX (Data Analysis Expressions) is a formula language used within the data model for calculations and dynamic aggregations. Essentially, Power Query shapes your data upfront, while DAX analyzes it inside reports.

4. What are calculated columns and measures, and when should they be used?

Ans:

Calculated columns create new data fields row by row and are stored in the model, useful for adding static data points. Measures are dynamic calculations evaluated on the fly, often used for summaries like totals or averages. Use calculated columns for static, row-level data, and measures for dynamic aggregations that respond to filters and slicers.

5. How do you implement row-level security (RLS) in Power BI?

Ans:

RLS restricts data access so users see only what they are allowed to. In Power BI Desktop, define roles and set table filters. After publishing to Power BI Service, assign users or groups to these roles. This ensures secure, role-based access and personalized reporting.

6. What are the ways to refresh data in Power BI?

Ans:

Data can be refreshed manually or automatically. Scheduled refreshes keep datasets up to date, while gateways enable refresh for on-premises sources. Full refresh reloads all data, whereas incremental refresh updates only new or changed records, improving efficiency for large datasets.

7. How can you improve Power BI report performance?

Ans:

Enhance performance by reducing the data model size, removing unnecessary columns, simplifying complex DAX formulas, and using aggregations. Limiting visuals per page and enabling query folding in Power Query, which pushes transformations to the data source, also speeds up report loading.

8. What are bookmarks in Power BI and how are they useful?

Ans:

Bookmarks capture a report page’s current state, including filters, slicers, and visuals. They allow interactive storytelling, guiding users through different scenarios or views. Combined with buttons and navigation, bookmarks make reports more dynamic and engaging.

9. What is the difference between DirectQuery and Import modes in Power BI?

Ans:

Import mode loads data into Power BI for fast querying and offline use but requires refreshes. DirectQuery queries data live from the source for real-time results but may be slower. The choice depends on data size, performance needs, and freshness requirements.

10. How do you manage relationships between tables in Power BI?

Ans:

Relationships connect tables to build a unified data model. Define them by matching columns (keys) across tables. Proper management, including cardinality, cross-filter direction, and inactive relationships, ensures accurate data flow in visuals and calculations for reliable analysis.

1. What is Power BI and how is it used in business reporting?

Ans:

Power BI is a Microsoft business analytics tool that transforms raw data into interactive reports and dashboards. Users can connect to multiple data sources, transform data, and build visualizations. Its key components include Power BI Desktop for report creation, Power BI Service for cloud-based sharing and collaboration, and Power BI Mobile for on-the-go access.

2. What is DAX in Power BI and why is it important?

Ans:

DAX (Data Analysis Expressions) is a formula language in Power BI for creating calculations, measures, and calculated tables. It offers functions for aggregations (SUM, AVERAGE), filtering (FILTER, ALL), and logical operations (IF, SWITCH). DAX is crucial for building dynamic and powerful data models.

3. What types of relationships can you create between tables in Power BI?

Ans:

Power BI supports one-to-one, one-to-many, and many-to-many relationships. One-to-one links one row in a table to a single row in another. One-to-many links one row to multiple rows in another table. Many-to-many allows multiple matches between tables, often requiring a bridging table for proper modeling.

4. How do Import and DirectQuery modes differ in Power BI?

Ans:

Import mode loads data into Power BI for fast querying and offline use but requires periodic refreshes. DirectQuery leaves data in the source and queries it live for real-time access, which can impact performance depending on the source system.

5. What are KPIs in Power BI and how are they used?

Ans:

Key Performance Indicators (KPIs) are visuals that track specific business metrics against goals. A KPI shows actual vs. target values and uses indicators like colors to display performance. KPIs help businesses quickly evaluate progress and identify areas needing attention.

6. What kinds of data sources are compatible with Power BI?

Ans:

Power BI connects to a wide range of data sources, including databases (SQL Server, Oracle, MySQL), cloud services (Azure, Snowflake, BigQuery), files (Excel, CSV, JSON, XML), and APIs or online platforms like SharePoint and Dynamics 365, making it highly versatile.

7. How does Power BI help track performance with KPIs?

Ans:

Power BI allows comparison of actual results against target values through KPI visuals. Each visual displays the tracked metric, the goal, and an indicator of progress, making it easy to monitor trends and quickly assess performance.

8. What is Power Query Editor and how is it used in Power BI?

Ans:

Power Query Editor is a tool for connecting, transforming, and cleaning data before loading it into the Power BI model. It enables actions like removing duplicates, changing data types, merging or splitting columns, and filtering records, simplifying data preparation without coding.

9. What are hierarchies in Power BI and why are they useful?

Ans:

Hierarchies organize data into levels for drill-down analysis. For example, a date hierarchy may include Year → Quarter → Month → Day, while a geographic hierarchy may include Country → State → City. Hierarchies improve navigation and enhance report interactivity.

10. What are the different data connectivity options available in Power BI?

Ans:

Power BI provides Import, DirectQuery, and Live Connection modes. Import brings data into Power BI for fast querying, DirectQuery connects to the source live, and Live Connection is used for SQL Server Analysis Services (SSAS) models, allowing real-time analysis without importing data.

1. How is Power BI different from Excel in terms of data analysis?

Ans:

While both Power BI and Excel analyze data, Power BI excels in creating interactive dashboards and visual reports. Unlike spreadsheet-based Excel, Power BI handles larger datasets, connects to multiple sources, offers real-time refresh, automation, and easy sharing making it ideal for modern business intelligence.

2. How does Power BI handle data extraction and transformation through Power Query?

Ans:

Power BI uses Power Query for ETL (Extract, Transform, Load) processes. It connects to data sources (extract), allows cleaning, filtering, merging, splitting, and reshaping (transform), and then loads the optimized data into the model (load). This ensures clean, structured data ready for analysis.

3. What is DAX in Power BI and what are some commonly used functions?

Ans:

DAX (Data Analysis Expressions) is a formula language for creating measures and calculated columns in Power BI. Similar to Excel formulas but more powerful, DAX supports functions like SUM(), AVERAGE(), CALCULATE(), and IF(), enabling dynamic calculations and advanced analytics within reports.

4. How are relationships between tables set up in Power BI?

Ans:

Relationships link tables to build a unified data model. Power BI supports one-to-one, one-to-many, and many-to-many relationships, defined by connecting common fields such as IDs or codes. This allows pulling data from multiple tables into a report accurately without manual merging.

5. What is the main difference between Import and DirectQuery modes in Power BI?

Ans:

Import mode loads data into Power BI for fast querying and offline work but requires scheduled refreshes. DirectQuery keeps data in the source and queries it live, offering real-time updates at the cost of potential performance delays. Import is suitable for most scenarios, while DirectQuery is ideal for constantly changing datasets.

6. How do you add and use slicers in Power BI reports?

Ans:

Slicers are interactive filters that control which data appears in visuals. Drag a field (e.g., “Region” or “Category”) into a slicer visual, and users can select options to dynamically filter the report. Slicers enhance interactivity without changing the report layout.

7. What is row-level security in Power BI and how do you use it?

Ans:

Row-Level Security (RLS) restricts data access so users see only relevant information. Implement it by creating roles and filter rules in Power BI Desktop, then assigning users to these roles in Power BI Service, ensuring secure, role-based access.

8. What can you do if your Power BI reports are running slowly?

Ans:

To improve performance, reduce the data model size, simplify DAX formulas, limit visuals per page, enable query folding in Power Query, and use aggregations or summary tables. Monitoring with the Performance Analyzer helps identify and resolve bottlenecks.

9. How do you publish and share Power BI reports with others?

Ans:

Publish reports from Power BI Desktop to Power BI Service. Share them by granting access to stakeholders, adding to a shared workspace, embedding in Teams or SharePoint, or setting up automated email subscriptions for easy distribution.

10. What does Power BI Service offer and how is it different from Power BI Desktop?

Ans:

Power BI Desktop is used to build and design reports locally, while Power BI Service is cloud-based for publishing, sharing, collaboration, and scheduled data refresh. Desktop is for development, and Service is for distribution and real-time access to dashboards.

1. What is Power BI and what are its key components?

Ans:

Power BI is a Microsoft business intelligence tool that enables users to model, transform, and visualize data through interactive dashboards and reports. Its core components are Power BI Desktop for report creation, Power BI Service for cloud-based sharing and collaboration, and Power BI Mobile for accessing reports on smartphones and tablets.

2. How is Power Query used to clean and transform data in Power BI?

Ans:

Power Query is Power BI’s tool for preparing data for analysis. It allows users to connect to multiple data sources and perform transformations like filtering rows, removing duplicates, changing data types, splitting columns, and merging tables all without writing code.

3. What is DAX in Power BI and how is SUM different from SUMX?

Ans:

DAX (Data Analysis Expressions) is Power BI’s formula language for creating measures, calculated columns, and tables. SUM() totals values in a single column, while SUMX() iterates over a table to perform calculations row by row before summing, making it useful for more complex scenarios.

4. What does a data model mean in Power BI and why is it important?

Ans:

A data model is a structured representation of your data, including tables, relationships, calculations, and metadata. It integrates data from multiple sources and allows connected, consistent analysis across visuals and reports.

5. How do you define relationships between tables in Power BI?

Ans:

Relationships connect tables based on common fields, such as IDs or keys. You can create them manually or let Power BI detect them automatically. Most relationships are one-to-many, linking one record in a table (e.g., Customer) to multiple records in another (e.g., Sales).

6. What are calculated columns in Power BI and how are they not the same as measures?

Ans:

Calculated columns add new fields to tables evaluated row by row and stored in the data model for use in visuals or relationships. Measures are dynamic calculations computed on demand in visuals, typically used for aggregations like totals or averages.

7. How is Power BI Service different from Power BI Desktop and what is each used for?

Ans:

Power BI Desktop is used locally to connect to data, transform it, and design reports. Power BI Service is the cloud platform for publishing reports, setting up data refresh schedules, managing access, and collaborating in shared workspaces.

8. How can you restrict users from seeing certain data in Power BI?

Ans:

Row-Level Security (RLS) controls data access based on user roles. You define roles and apply filters so that users only see relevant data, such as a regional manager viewing sales for their own region.

9. What is the difference between DirectQuery and Import mode and when would you use each?

Ans:

Import mode loads data into Power BI for fast performance but requires scheduled refreshes. DirectQuery queries the source live for real-time data, suitable for large or frequently updated datasets, though it may be slower.

10. Can you describe a time you built a complex dashboard and solved performance issues?

Ans:

While building a dashboard combining sales, inventory, and customer metrics from multiple sources, performance lagged due to data volume and complex DAX. To optimize, I reduced visuals per page, removed unused columns, replaced calculated columns with measures, and used summary tables with pre-aggregated data, significantly improving report speed.
