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
Prototype work means building things that haven't been built many times before. Tell me about a time you assembled something without a finished set of instructions.
What they are checking: Whether they can work carefully from incomplete documents, which is normal on new products.
Tell me about a time you worked closely with an engineer. How did it go?
What they are checking: Whether they can communicate with engineers as a partner and not just take orders.
Tell me about something you built that you were especially proud of.
What they are checking: Whether they care about craftsmanship and take ownership of their work.
What would you do
You're building a prototype and the drawing seems wrong. What do you do?
What they are checking: Whether they raise the issue with engineering instead of quietly fixing it, since feedback is the point of prototyping.
The design changes halfway through your build. How do you handle that?
What they are checking: Whether they stay patient and organized when plans change often, which comes with prototype work.
How do you make sure you're doing the job safely when the process isn't fully set yet?
What they are checking: Whether they think about safety when no standard work exists yet to guide them.
About the work
How comfortable are you reading schematics and mechanical drawings?
What they are checking: Whether they can build accurately from technical documents that may still be changing.
How do you write down what you found during a prototype build so engineers can use it?
What they are checking: Whether they capture build problems clearly, which helps design get ready for production.
What tools and equipment have you used for electrical or mechanical assembly?
What they are checking: Whether their hands-on skills cover the range of tasks a prototype shop needs.
How do you keep track of parts and revisions so the wrong version doesn't end up in a build?
What they are checking: Whether they manage revision control carefully, since mixing versions ruins a prototype's test results.
