Your question is Troubleshoot Intermittent Failures. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
How would you troubleshoot a distributed application that is experiencing intermittent failures? Explain how you would organize the investigation, coordinate the relevant engineering and operations stakeholders, use logs, metrics, traces, and deployment history, and distinguish among dependency, networking, capacity, configuration, and data-consistency issues. Describe your immediate mitigation, evidence-driven root-cause analysis, communication cadence, and follow-up actions to prevent recurrence.
