Welcome to your interview.
The question is on your right: Ensuring Data Integrity. 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.
How do you ensure data completeness and integrity when working with cross-functional teams and external data management groups?
