Safety, human factors, tool control, FOD, shift handover, troubleshooting approach and proper use of maintenance documentation are common topics.
Do not invent an answer to a technical question. A sound approach is to say you would verify the correct maintenance data, confirm configuration and follow the applicable procedure.
Prepare short examples from your real experience: how you followed a defect, what safety precautions you used, how you handed over a shift and how you reduced error risk.
