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 caught a problem with a blueprint or a part before it turned into scrap.
What they are checking: attention to detail and willingness to flag issues rather than just run the job as told
Describe a time you had to build or use a jig or fixture to hold an odd-shaped or difficult part.
What they are checking: real experience with workholding beyond standard vise setups
Tell me about a time you had to deburr, file, or polish a part to get it to final spec. What tools did you use?
What they are checking: hands-on finishing skill beyond just running the CNC cycle
Tell me about a time instructions from a supervisor, a blueprint, and a schedule didn't quite line up. How did you sort it out?
What they are checking: ability to reconcile conflicting information without stalling production
What would you do
If you're mid-run and you notice the part is starting to drift out of tolerance, what do you do right then?
What they are checking: judgment about stopping production versus pushing through, and whether they understand the cost of scrap
You're running two jobs on a tight schedule and one machine goes down for routine maintenance. How do you handle it?
What they are checking: ability to juggle production priorities and communicate delays
How do you keep track of labor reports, material issues, scrap reports, and kit lists during a shift?
What they are checking: organizational habits and honesty around paperwork that affects scheduling and cost tracking
About the work
Walk me through how you'd set up a Haas mill for a new job, starting from a blank table.
What they are checking: whether the candidate actually knows the full setup sequence, not just how to run a machine someone else set up
How do you decide what tooling, speeds, and feeds to use for a given material and operation?
What they are checking: depth of hands-on machining knowledge versus memorized rules
How do you use calipers and micrometers to verify a part is within spec, and how do you know when to trust the measurement versus re-check it?
What they are checking: practical measuring skill and awareness of measurement error
Have you downloaded and edited a CNC program directly at the machine? What kind of edits have you made and why?
What they are checking: comfort level editing G-code on the fly versus relying entirely on programmers
What does your daily routine look like for maintaining the machine, like coolant, chips, and general upkeep?
What they are checking: whether they treat basic maintenance as part of the job or something to skip
What's the toughest math or geometry problem you've had to work through on the shop floor to figure out a cut or setup?
What they are checking: real application of math skills to machining, not classroom knowledge
