Welcome to your interview.
The question is on your right: Zero-Downtime Deployment Strategy. 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 responsible for deploying a critical production service that supports customer-facing traffic. The team wants to reduce release risk while still shipping frequently, and you need an approach that balances speed, safety, and operational clarity.
What strategies do you use for rolling updates, canary releases, and ensuring zero-downtime deployments? How do you decide between them, define success criteria, and prepare rollback plans if the release degrades production?
