Welcome to your interview.
The question is on your right: Secure Auth Across Microservices. 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 implement secure authentication and authorization across microservices? Explain the role of JWTs and OAuth2.
