About the role
This interview focuses on maintaining haul trucks, loaders, excavators and other mobile mining equipment in demanding conditions. The panel wants a technician who diagnoses methodically, controls hazardous energy, completes reliable repairs and leaves records that prevent repeat downtime.
How to prepare
- Review systematic diagnosis for diesel, hydraulic, braking, cooling and basic electrical faults.
- Prepare examples of planned services and urgent breakdowns where you verified the repair before release.
- Revise isolation, blocking, safe lifting and stored-energy controls for mobile equipment.
- Choose an example where inspection findings prevented a larger failure.
- Practise reading a simple hydraulic or electrical schematic and explaining your test sequence.
Common mistakes
- Listing possible parts without describing a logical test sequence.
- Skipping isolation or stored-energy controls because a repair seems quick.
- Claiming a machine is fixed without explaining the operational checks used.
- Leaving vague job notes that cannot support planning or further diagnosis.
