🧠 SQL Interview Question (Category Contribution % - Tricky)
📌
sales(category, product_id, revenue)
❓ Ques :
👉 For each category, calculate percentage contribution of each product’s revenue within that category
👉 Return category, product_id, revenue, contribution_percentage
🧩 How Interviewers Expect You to Think
• Calculate total revenue per category 📊
• Divide product revenue by category total
• Use window functions (SUM OVER)
💡 SQL Solution
SELECT
category,
product_id,
revenue,
(revenue * 100.0) / SUM(revenue) OVER (
PARTITION BY category
) AS contribution_percentage
FROM sales;
🔥 Why This Question Is Powerful
• Tests real business KPI calculation skills 🧠
• Evaluates understanding of window functions with aggregation
• Very common in Amazon, Flipkart, analytics roles
❤️ React if you want more real interview-level SQL questions 🚀
✅ Power BI Scenario-Based Questions 📊⚡
🧮 Scenario 1: Measure vs. Calculated Column
Question: You need to create a new column to categorize sales as “High” or “Low” based on a threshold. Would you use a calculated column or a measure? Why?
Answer: I would use a calculated column because the categorization is row-level logic and needs to be stored in the data model for filtering and visual grouping. Measures are better suited for aggregations and calculations on summarized data.
🔁 Scenario 2: Handling Data from Multiple Sources
Question: How would you combine data from Excel, SQL Server, and a web API into a single Power BI report?
Answer: I’d use Power Query to connect to each data source and perform necessary transformations. Then, I’d establish relationships in the data model using the Manage Relationships pane. I’d ensure consistent data types and structure before building visuals that integrate insights across all sources.
🔐 Scenario 3: Row-Level Security
Question: How would you ensure that different departments only see data relevant to them in a Power BI report?
×Answer:× I’d implement ×Row-Level Security (RLS)× by defining roles in Power BI Desktop using DAX filters (e.g., [Department] = USERNAME()), then publish the report to the Power BI Service and assign users to the appropriate roles.
📉 Scenario 4: Reducing Dataset Size
Question: Your Power BI model is too large and hitting performance limits. What would you do?
Answer: I’d remove unused columns, reduce granularity where possible, and switch to star schema modeling. I might also aggregate large tables, optimize DAX, and disable auto date/time features to save space.

🚀 Power BI Interview Questions Cheat Sheet (Must-Know for Data Analysts)
Power BI Interview Questions with Answers
Question: How would you write a DAX formula to calculate a running total that resets every year?
RunningTotal =
CALCULATE( SUM('Sales'[Amount]),
FILTER( ALL('Sales'),
'Sales'[Year] = EARLIER('Sales'[Year]) &&
'Sales'[Date] <= EARLIER('Sales'[Date])))
Question: How would you manage and optimize Power BI reports that need to handle very large datasets (millions of rows)?
Solution:
1. Use DirectQuery mode if real-time data is needed.
2. Pre-aggregate data in the data source.
3. Use dataflows for preprocessing.
4. Implement incremental refresh.
Question: What steps would you take if a scheduled data refresh in Power BI fails?
Solution:
Check the Power BI service for error messages.
Verify data source connectivity and credentials.
Review gateway configuration.
Optimize and simplify the query.
Question: How would you create a report that dynamically updates based on user input or selections?
Solution: Use slicers and what-if parameters. Create dynamic measures using DAX that respond to user selections.
Question: How would you incorporate advanced analytics or machine learning models into Power BI?
Solution:
Use R or Python scripts in Power BI to apply advanced analytics.
Integrate with Azure Machine Learning to embed predictive models.
Use AI visuals like Key Influencers or Decomposition Tree.
Question: How would you integrate Power BI with other Microsoft services like SharePoint, Teams, or PowerApps?
Solution: Embed Power BI reports in SharePoint Online and Microsoft Teams. Use PowerApps to create custom forms that interact with Power BI data. Automate workflows with Power Automate.
