About your past
Tell me about an engineering project from school or a past job that you are proud of. What was your part?
What they are checking: Whether they can explain their own contribution clearly and honestly, not just the team's result.
Tell me about a time you had to learn something technical quickly with little guidance.
What they are checking: Whether they can teach themselves and ask good questions, which interns at a plant need to do every day.
How comfortable are you working on a manufacturing floor around machines and safety rules?
What they are checking: Whether they will follow plant safety rules and be comfortable spending real time on the production floor.
Tell me about a time you presented your work to people senior to you.
What they are checking: Whether they can share results clearly at the end of the summer, which is often how interns are judged.
What do you hope to learn from a summer at a plant in Lanark, and what kind of engineering do you want to do after school?
What they are checking: Whether their goals fit a hands-on manufacturing internship and whether they might return after graduation.
What would you do
If you were asked to cut the time it takes to assemble a product, how would you start?
What they are checking: Whether they would observe and measure the work first instead of guessing at improvements from a desk.
You notice an operator doing a step differently than the work instruction says. What do you do?
What they are checking: Whether they approach operators with curiosity and respect, since the operator may know something the instruction misses.
About the work
What CAD software have you used, and what is the most complex thing you modeled?
What they are checking: Whether they can start on drawing and fixture work without a long ramp-up during a short internship.
How would you explain tolerances on a drawing to someone who has never read one?
What they are checking: Whether they understand the basics well enough to teach them, which shows real grasp rather than memorized terms.
What is one way you have used data or a spreadsheet to make an engineering decision?
What they are checking: Whether they back up ideas with numbers, which is how an intern earns trust from experienced engineers.
