About your past

Tell me about a time you fixed a mechanical or electrical problem outside your main trade.

What they are checking: Whether they can handle the basic mechanical and electrical work this role also includes.

If you're hired as an apprentice, how would you approach learning from journey workers?

What they are checking: Coachability and initiative, since the role may be filled at the apprentice level.

Describe a time you found the root cause of a repeat failure instead of just fixing it again.

What they are checking: Whether they think about why something keeps failing, which reduces forced outages.

About the work

Walk me through calibrating a pressure transmitter, start to finish.

What they are checking: Core instrument skills and attention to steps like isolation, as-found readings and documentation.

A control loop at the plant is oscillating. How do you figure out whether it's the instrument, the valve or the tuning?

What they are checking: Structured troubleshooting across the whole loop instead of guessing at one component.

What plant control systems have you worked on, and how comfortable are you making changes in them?

What they are checking: Experience with DCS or PLC platforms and respect for the risk of changing live controls.

How do you make sure equipment is safe before you start work on an instrument tied into a live process?

What they are checking: Energy isolation and process safety habits, which matter most when working on live systems.
