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 a time you made a scrap part. What happened and what did you change afterward?
What they are checking: Whether they own mistakes honestly and learn a habit from them, which matters in a safety-sensitive, quality-driven shop.
Tell me about a time you had to communicate a problem to your supervisor that would delay a job.
What they are checking: Whether they raise issues early and clearly so the shop can adjust, instead of hiding delays.
What would you do
Halfway through a production run, your in-process check shows a dimension drifting toward the limit. What do you do?
What they are checking: Whether they stop and find the cause, like tool wear or heat, before making scrap instead of running until it fails.
You pull material from staging and something about it doesn't match the WOPAC. What do you do?
What they are checking: Whether they verify material before cutting and raise discrepancies instead of assuming it is close enough.
A program you just downloaded from the programmer looks off when you dry-run it. How do you handle that?
What they are checking: Whether they catch program errors safely before cutting and communicate with the programmer rather than editing blindly.
About the work
Walk me through setting up a 3-axis mill for a new job, from reading the work order to running the first part.
What they are checking: Whether they follow a disciplined setup sequence including tooling, fixture, offsets and first article, not just hitting cycle start.
How do you align a vise and locate the center of a fixture, and how do you check that you got it right?
What they are checking: Whether they have real hands-on setup skill and verify their work with indicators instead of trusting a guess.
You're machining engineered plastics here, not just metal. What changes when you cut plastic, and what problems do you watch for?
What they are checking: Whether they understand heat, chip control, part movement and dimensional changes that make plastics behave differently from steel.
Which manual gauges do you use most, and how do you make sure your measurements are accurate?
What they are checking: Whether they handle calipers, micrometers and pins correctly and know how technique affects a reading.
What does 5S mean to you on a machine, day to day?
What they are checking: Whether they treat organization and cleanliness as part of quality and safety rather than a cleanup chore.
What daily and monthly preventive maintenance do you do on a CNC, and why does it matter?
What they are checking: Whether they care for their equipment and understand that skipped maintenance causes downtime and bad parts.
