About your past
The posting says you would design or alter machines with manufacturing feasibility, cost and operation in mind. Tell me about a design where you balanced all three.
What they are checking: Whether they make practical engineering tradeoffs instead of designing only for function.
Tell me about a design that failed in testing or in the field. What did you learn?
What they are checking: Honest reflection and whether they learned to design and test more carefully.
How do you work with electrical and controls engineers during a design?
What they are checking: Whether they coordinate with other disciplines early enough to prevent late integration problems on the machine.
What would you do
The shop says your part cannot be made as drawn. What do you do?
What they are checking: Whether they listen to manufacturing and redesign instead of defending the drawing.
A customer wants a custom modification on a standard machine. How do you approach it?
What they are checking: Whether they protect the base design while meeting the customer's need.
About the work
How would you design a new section for a corrugator or sheeter that needs to run at high speed?
What they are checking: Machine design thinking about stiffness, dynamics, wear and maintenance at speed.
What CAD software do you use, and how do you manage large assemblies in it?
What they are checking: Tool fluency for large machinery models with many parts.
How do you size a bearing, shaft or drive component, and what do you check by hand versus in software?
What they are checking: Fundamental machine design skill and whether they verify software results.
How do you apply tolerances so parts fit without making them too expensive to machine?
What they are checking: Whether they understand GD&T well enough to keep parts functional without driving up machining cost.
How do you design guarding and safety into a machine?
What they are checking: Machine safety awareness built into mechanical design from the start.
