About your past

Tell me about the commercial equipment you have repaired. What kinds of mechanical and electrical problems have you diagnosed?

This role includes on-call, after-hours, holiday and weekend repairs. How have you handled a schedule like that before?

What they are checking: Whether they understand the on-call commitment and have shown they can keep it reliably.

Tell me about a repair that took you much longer than expected. What made it hard and what did you learn?

What they are checking: Whether they stay persistent on tough problems and learn from them rather than giving up.

How do you keep your service paperwork and time records accurate when you are running between several calls in a day?

What they are checking: Whether they document work promptly, since billing and warranty claims depend on those records.

You arrive at a grocery store and the deli manager is upset that their slicer has been down all morning. How do you handle the first few minutes?

About the work

A restaurant's dishwasher is not reaching rinse temperature during a lunch rush. Walk me through how you would troubleshoot it.

What they are checking: Whether they diagnose step by step using meters and readings instead of swapping parts until something works.

How do you check a circuit safely before you start working on a piece of equipment?

What they are checking: Whether they follow lockout and electrical safety every time, since shortcuts here cause serious injuries.

How do you read a wiring diagram for a piece of equipment you have never worked on?

What they are checking: Whether they can work from schematics, which matters across ovens, refrigeration and ware washing equipment.

What do you know about refrigeration basics, like how a compressor and refrigerant cycle work?
