Likely interview questions for this role
Written from this job description, not a generic list. Each one notes what the interviewer is really checking.
About your past
Tell me about the manufacturing equipment you've maintained. What kinds of systems were you responsible for?
What they are checking: Whether their past equipment experience transfers to a packaging plant with mechanical, electrical, and fluid power systems.
Tell me about a time you followed an established procedure even though you thought there was a faster way.
What they are checking: Whether they respect procedures in a role built on them, and know how to suggest changes the right way.
How do you document a repair so the next tech knows what happened?
What they are checking: Whether they write notes that help the next person, since good repair history saves hours on repeat failures.
Tell me about a time you learned a new machine quickly. How did you get up to speed?
What they are checking: Whether they can teach themselves new equipment, because every plant has machines they have never touched.
What would you do
You're halfway through a PM and production asks you to stop and fix a different machine. What do you do?
What they are checking: Whether they can reprioritize while making sure the half-done PM is safely closed out and not forgotten.
A coworker skips lockout to clear a quick jam. What do you do?
What they are checking: Whether they will speak up about safety with a peer, since one skipped lockout can cost someone a hand.
About the work
Walk me through how you approach a machine that won't start at the beginning of a shift.
What they are checking: Whether they have a step-by-step way to troubleshoot power, controls, safeties, and interlocks rather than guessing.
How do you read an electrical schematic to track down a failed component?
What they are checking: Whether they can actually use prints to troubleshoot rather than relying only on experience with one machine.
What do you check during a preventive maintenance on a gearbox or conveyor drive?
What they are checking: Whether they know the specifics of a good PM, like oil condition, temperature, vibration, alignment, and belt or chain wear.
What tools and meters are you comfortable using on the job?
What they are checking: Whether they have hands-on ability with multimeters, gauges, and precision tools that the job will require from the first week.
