Your question is Basic DAX vs SQL Measures. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Analysts moving from SQL to Power BI are often expected to explain how DAX works at a practical level. Interviewers usually want to know whether you understand how DAX differs from standard SQL aggregation logic.
Explain how to use basic DAX in Power BI. Your answer should cover:
SUM, COUNT, DIVIDE, and CALCULATE are usedGROUP BYKeep the explanation at an interview level: define the core concepts clearly, show a few short examples, and connect them to SQL concepts the interviewer already knows. You do not need advanced time intelligence or complex filter propagation details, but you should be precise about when a measure recalculates versus when a calculated column is stored.
