Role and Technical Knowledge
- 1
What is the difference between preventive, predictive and breakdown maintenance?
Explain that preventive is scheduled, predictive uses condition monitoring like vibration or thermography, and breakdown is reactive after failure. Give a plant example for each.
- 2
How would you troubleshoot a hydraulic system that has lost pressure?
Cover checking fluid level, pump, relief valve, filters, leaks and actuator seals in a logical sequence. Mention using pressure gauges and following the circuit diagram.
- 3
What is the role of a PLC in an automobile or metal manufacturing line?
Describe how PLCs read inputs from sensors and control outputs like motors, valves and conveyors. Mention ladder logic, I/O modules and safety interlocks.
- 4
What does OEE measure and why is it important for maintenance?
Define OEE as availability times performance times quality. Explain how maintenance improves availability and reduces downtime losses.
Practical Scenarios
- 5
A critical motor on the production line trips repeatedly. How do you handle it?
Start with safety isolation, then check overload settings, winding resistance, supply voltage, load and cooling. Suggest temporary backup and permanent fix after root cause analysis.
- 6
You notice a minor oil leak under a machine during your shift. What do you do?
Show that you report it, tag the area, assess risk, and schedule repair before it becomes a safety or breakdown issue. Mention documenting in CMMS.

Production wants a machine restarted immediately after a breakdown, but safety checks are pending. How do you respond?
Emphasise that safety cannot be compromised. Explain that you would communicate clearly, complete essential checks quickly, and get approval before restart.
- 8
How would you reduce repeated failures of a conveyor belt in a foundry or rolling mill area?
Talk about root cause analysis, checking alignment, tension, idler condition, material build-up and temperature. Suggest a preventive schedule and condition monitoring.
Behavioural and Teamwork
- 9
Tell me about a time you worked in a team to solve a problem.
Use a STAR structure with a specific project or college event. Highlight your role, coordination and the measurable outcome.
- 10
