Welcome to your interview.
The question is on your right: BI Tools and ETL Comfort. 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.
Which BI tools or programming languages are you most comfortable using for data visualization and ETL processes?
