Walk me through how you’d diagnose an intermittent hardware failure that only appears under load.
Employers ask this question to understand your troubleshooting structure, patience, and ability to isolate variables under realistic conditions. In your answer, outline a step-by-step approach, tools you’d use, how you recreate load, and how you document findings for others.
Answer Example: "I’d start by reproducing the issue under controlled load—using stress tools and monitoring temperature, power draw, and logs. Then I’d isolate variables by swapping known-good components and using a thermal camera and multimeter to narrow it down. I document each step with timestamps and photos so engineering can reproduce. If I find a root cause, I validate it with at least two repeat tests before closing."
