You inherit a legacy CI/CD pipeline with zero documentation, and the person who built it left the company months ago. How do you approach understanding it and safely making your first change?

IntermediateCI/CD8 min

How would you decide whether to gradually refactor a legacy pipeline versus rewriting it from scratch?

How do you balance the time investment in fully understanding a legacy system against the pressure to just make the requested change quickly?

You've proposed a robust, well-architected solution to a problem, but your manager wants a quick, hacky fix instead because the problem is genuinely minor. Are they wrong, or are you over-engineering?

You inherit ownership of a system whose fundamental architecture you think was the wrong call — not a small detail, a core design decision. How do you handle this, given the system is already in production?

You've just joined a team responsible for critical infrastructure, and there's essentially no documentation — the previous engineers who understood it have all left. How do you approach getting up to speed safely?

IntermediateDevops6 min

Your organization depends heavily on an internal tool maintained by exactly one engineer, who's showing clear signs of burnout and has hinted they might leave. How do you handle this before it becomes a crisis?
