Welcome to your interview.
The question is on your right: Debugging Production Data Pipelines. 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're responsible for a production data pipeline, and something starts going wrong after it has been running normally. You need a clear way to isolate the issue, limit downstream impact, and restore confidence in the data before making broader changes.
How do you approach debugging issues in production systems?
