30. Interview Questions and Answers

By Last updated:

Now, interview preparation! This module has frequently asked questions and model answers. Remember, the interview happens in English, so the answers are kept in clean, professional English. Do not memorise them – understand them and say them in your own words with an example from your project.

Live story: The interview on Thursday

Suppose an Infosys client team has a Power BI interview for you on Thursday. They will ask: "What is a measure? Explain CALCULATE. How does RLS work? Walk me through your project." This chapter gives clear model answers and, at the end, what a company expects from you in week 1.

All numbers in this story are fictional practice data.

These are frequently asked questions in data analyst and Power BI developer interviews. Answer in your own words, and whenever possible add a short example from your own project.
