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.

✅ 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.

Data Analytics Interview Preparation
[Questions with Answers]

How did you get your job?

I was hired after an internship. 
To get the internship, I prepared a bunch for general Python questions (LeetCode etc.) and studied the basics of machine learning (several different algorithms, how they work, when they're useful, metrics 
to measure their performance, how to train them in practice etc.). 

To get the internship I had to pass a technical interview as well as a take-home machine learning (ML) exercise. Then, it was just a question of doing a good job in the internship! 

What are your data related responsibilities in your job? 

I work on our recommendation system. It’s deep learning based. I work on a lot of features to try and 
improve it (reinforcement learning & NLP etc). Since I'm in a start-up, it's also up to our team to put the models we design into production. So, after a phase of research & development and model design, in notebooks, it's time to create a real pipeline, by creating scripts. 
This enables us to define, train, replace, compare and check the status of the models in production. It's basically all in Python, using Keras/TensorFlow, Pandas, Scikit-learn and NumPy. We also do a lot of analysis for the business team to help them compute metrics of interest (related to 
revenue, acquisition etc.). For that, we use an external utility called Metabase. It is is hooked up to our database where we write SQL queries and visualize the results and create dashboards (using 
Tableau/Looker etc). 
I would say my role is quite "full-stack" since we are all involved from the phase of R&D to deployment on our cluster. 

Was it difficult to get this role?

I got hired after an internship. If you come from a scientific background, it's not that hard to transition into data science. All the math is something you will probably have seen already (especially if you're 
doing maths or physics). So, with some preparation and coding practice, you can start applying to internships. 
It took me maybe a month or two of preparation to get some basic ideas of the typical Python data stack (Pandas, Keras, SciKit-learn etc) before I started to send out CVs. Then, if you get an internship, try your best to do the best you can and then maybe you'll be hired after!

🧑‍💼 Interviewer: What's the difference between VLOOKUP and HLOOKUP in Excel?

👨‍💻 Me: VLOOKUP searches vertically down columns (great for column-based data like employee lists), while HLOOKUP searches horizontally across rows (ideal for row-based setups like category headers).

✔ Key Differences:
– VLOOKUP: Looks for a value in the first column of a range, returns from the same row in a specified column—syntax: =VLOOKUP(lookup_value, table_array, col_index_num, [range_lookup]). Use for vertical data; e.g., find salary by ID in a table.
– HLOOKUP: Looks for a value in the first row of a range, returns from the same column in a specified row—syntax: =HLOOKUP(lookup_value, table_array, row_index_num, [range_lookup]). Use for horizontal data; e.g., pull metrics by month across a header row.

📌 Example:
Vertical sales table (IDs in col A, amounts in B): VLOOKUP(ID, A:B, 2, FALSE) gets amount.
Horizontal (months in row 1, sales in row 2): HLOOKUP("Jan", 1:3, 2, FALSE) gets Jan sales.

💡 VLOOKUP's more common (90% of lookups), but both support exact (FALSE) or approx (TRUE) matches—switch to XLOOKUP in modern Excel for bidirectional flexibility!

7 Misconceptions About Data Analytics (and What’s Actually True): 📊🚀

❌ You need to be a math or statistics genius
✅ Basic math + logical thinking is enough. Most real-world analytics is about understanding data, not complex formulas.

❌ You must learn every tool before applying for jobs
✅ Start with core tools (Excel, SQL, one BI tool). Master fundamentals — tools can be learned on the job.

❌ Data analytics is only about numbers
✅ It’s about storytelling with data — explaining insights clearly to non-technical stakeholders.

❌ You need coding skills like a software developer
✅ Not required. SQL + basic Python/R is enough for most analyst roles. Deep coding is optional, not mandatory.

❌ Analysts just make dashboards all day
✅ Dashboards are just one part. Real work includes data cleaning, business understanding, ad-hoc analysis, and decision support.

❌ You need huge datasets to be a “real” data analyst
✅ Even small datasets can provide powerful insights if the questions are right.

❌ Once you learn analytics, your learning is done
✅ Data analytics evolves constantly — new tools, business problems, and techniques mean continuous learning.
