Welcome to your interview.
The question is on your right: Ensuring Data Integrity in Mapping. 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 accuracy and data integrity when performing complex data mapping and translation tasks?
