Welcome to your interview.
The question is on your right: Ensure Distributed Data Consistency. 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.
You are leading an engineering initiative that spans multiple services and data stores, where the same business event can be reflected in several systems at different times. You need a clear execution approach so the team can maintain reliable data consistency without slowing delivery or creating unacceptable operational risk.
How would you ensure data consistency across distributed systems?
