Likely interview questions for this role

Written from this job description, not a generic list. Each one notes what the interviewer is really checking.

Behavioral

Tell me about a time you had to edit G-code or M-code on the fly at the machine to fix a problem during a run.

real hands-on troubleshooting experience versus theoretical knowledge

Describe a program you improved for efficiency or reliability after it was already running in production. What did you change and how did you measure the improvement?

initiative and understanding of cycle time, tool wear, and material removal optimization

Tell me about a time an operator was struggling to run a program you wrote. How did you handle training them?

ability to communicate technical detail to less experienced staff and patience under pressure

Tell me about a time you disagreed with an engineer about how a part should be designed for manufacturability. How did that conversation go?

collaboration style with engineering and ability to advocate for machinability without being difficult

Technical

Walk me through how you'd program a part that starts as steel bar stock and needs complex geometry held to close tolerances on a 4-axis lathe with live tooling.

whether the candidate actually understands the full workflow from raw stock to finished part, not just button-pushing

What CAM software have you used day to day, GibbsCAM, MasterCAM, or Partmaker, and where does your comfort level actually stop?

honesty about depth of tool knowledge versus surface familiarity

How do you decide on tooling and fixturing for a brand new job when you're starting from a casting versus starting from bar stock?

depth of process planning knowledge across different material starting points

How have you used SolidWorks in your programming work, and how do you handle a job where the model doesn't quite match the print?

practical CAD fluency and judgment when drawings and models conflict

What's your experience with SAP or a similar ERP/MRP system for things like tool crib inventory or job routing?

whether they've actually worked inside the administrative side of the job, not just the machine side

How do you document your setups and tooling library so someone else could pick up your job if you weren't there?

whether they build for the team versus keeping tribal knowledge in their own head

Situational

Say you're proving out a new program on a horizontal machining center and the part is coming out slightly out of tolerance on one feature. What's your process for chasing that down?

systematic troubleshooting approach versus guessing or trial and error

Have you dealt with a DNC system going down or losing communication between a machine and the server? What did you do?

real exposure to shop floor networking issues, not just machine-level programming

A machine is causing repeated downtime and nobody can pin down whether it's the program, the tooling, or the machine itself. How would you go about isolating the cause?

root cause analysis skill across program, tooling, and mechanical variables
