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 tough mold repair you completed. What made it hard and how did you get it done?
What they are checking: Depth of experience and problem solving when a repair does not go by the book.
How do you work with process technicians during a tool tryout when parts are not meeting spec?
What they are checking: Collaboration with process techs to decide whether the fix belongs in the steel or the process.
What would you do
Production needs a cavity change done before second shift, but you find a cracked ejector pin while the mold is open. What do you do?
What they are checking: Balancing schedule pressure against tool safety and communicating the tradeoff to production.
Why does recording repair history on each tool matter, and how do you do it?
What they are checking: Whether they see documentation as part of the job that helps spot recurring tool problems.
About the work
A mold is producing parts with flash on one cavity only. Walk me through how you would track down the cause.
What they are checking: Real troubleshooting order on injection molds, separating tool damage from process settings.
How do you verify the shutoffs and parting line on a mold after a repair?
What they are checking: Hands-on knowledge of fitting and spotting, which decides whether a repaired tool runs good parts.
Which measuring tools do you reach for when checking a core insert, and how do you make sure your readings are right?
What they are checking: Comfort with calipers, micrometers, gauge blocks and indicators, plus the habit of trusting but checking measurements.
What CNC and conventional equipment have you set up and run yourself?
What they are checking: Whether they can make their own components on lathes, mills and grinders rather than waiting on others.
How do you read a mold blueprint to plan a repair when the print and the actual tool do not match?
What they are checking: Whether they notice and resolve discrepancies instead of building to a wrong print.
What do you check before signing off that a tool is ready for production?
What they are checking: A consistent production-readiness routine that prevents a tool from failing on the press.
