Start with the equipment
Ask which lines and mechanisms the candidate worked on personally. An employer's name is no substitute for understanding the work.
Explore a real fault
Discuss a specific incident: symptoms, diagnostic sequence, cause and actions taken.
Clarify individual responsibility
Separate the candidate's work from colleagues’ contributions. Understand when they acted independently and when they called a specialist.
Discuss safe working
Ask how safe access and return to service were organised. An interview does not replace the checks and training required on site.
Match expectations
Discuss shifts, call-outs and preventive maintenance. Candidates should understand everyday work as well as interesting repairs.
Write a useful assessment
Record concrete examples, open questions and topics for the technical meeting. Avoid judging experience only by years served.
