Welcome to your interview.
The question is on your right: Data Integrity in Distributed Systems. 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.
What strategies do you use to ensure data integrity and transactional consistency across distributed database systems in healthcare payment workflows?
