Welcome to your interview.
The question is on your right: Design a Production Rollback Plan. 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 preparing a production deployment for a critical backend service, and you want a clear plan in case the release causes errors, latency spikes, or downstream failures after traffic is shifted. The goal is not just to undo the change, but to restore service safely, minimize rider and driver impact, and avoid making the incident worse during a high-pressure rollout.
How would you design a rollback plan for a failed production deployment?
