Welcome to your interview.
The question is on your right: Prevent Repeat Incidents. 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 the EM for a product engineering team that has had three production incidents in the last quarter. The incidents were resolved quickly, but the same root causes are starting to reappear in adjacent services, and leadership is worried the team is treating postmortems as paperwork instead of learning. You also have a release train coming up, so any new process has to improve reliability without slowing delivery to a crawl.
How do you make sure your team learns from incidents and doesn't repeat the same mistakes?
