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

The posting welcomes candidates with limited experience but strong mechanical aptitude. Tell me about something mechanical you have built or fixed.

What they are checking: Whether they have the hands-on aptitude and curiosity to learn machining quickly.

This is second shift. Tell me how you handle working with less support around.

What they are checking: Whether they can work independently and solve problems without day shift engineers nearby.

What would you do

You notice parts are drifting toward the edge of tolerance late in the run. What do you do?

What they are checking: Whether they act before parts go bad instead of waiting for scrap.

About the work

You will do full CNC setups on lathes or mills for castings, including tooling, work holding and fixturing. Walk me through a setup from start to first part.

What they are checking: Whether they understand the whole setup process, not just running a machine someone else set up.

What makes machining castings different from machining bar stock?

What they are checking: Whether they understand variation, hard spots and fixturing challenges with castings.

Your first part is out of tolerance on a bore. How do you figure out why and fix it?

What they are checking: Whether they troubleshoot with measurement, offsets and tool wear instead of guessing.

Which precision gages are you comfortable with, like calipers, micrometers, bore gauges and gauge blocks?

What they are checking: Whether they can measure accurately enough to hold tight tolerances.

Look at a print with a GD&T callout for position. What is it telling you?

What they are checking: Whether they can read blueprints and GD&T well enough to make good parts.

How comfortable are you making offsets and minor program edits?

What they are checking: Whether they can adjust programs safely without causing a crash or scrap.

How do you use an overhead hoist safely to load a heavy casting?

What they are checking: Whether they follow lifting safety, since heavy loads cause serious injuries.
