Welcome to your interview.
The question is on your right: Power BI Relationships and DAX. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
In Microsoft Power BI, how do you handle complex relationships between tables, and what is your approach to writing efficient DAX measures?
