Welcome to your interview.
The question is on your right: Data Lineage and Quality Assurance. 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.
Can you describe your experience with data lineage and how you ensure data quality across multiple sources?
