Welcome to your interview.
The question is on your right: Incremental Loads and Time Travel. 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.
Explain how you would implement incremental loads and use time travel to validate data changes in A healthcare technology's pipelines.
