Welcome to your interview.
The question is on your right: Saga vs Two-Phase Commit. 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 would you handle distributed transactions across microservices, and when would you choose the Saga pattern over 2PC for EPAM Systems delivery?
