Likely interview questions for this role
Written from this job description, not a generic list. Each one notes what the interviewer is really checking.
Behavioral
Tell me about a class project or personal project where you had to design a mechanical part from scratch. What did you use to model it and how did you know it would work?
whether the candidate has done real hands-on design work versus just coursework theory
Tell me about a time you had to analyze data from an experiment or test and it didn't match what you expected. What did you do next?
comfort with ambiguous results and whether they dig into root cause rather than dismiss it
Describe a group project where people had different opinions on the right approach. How did the team land on a decision?
ability to function on a cross-functional team without needing to be right or in charge
Tell me about a time something you built or tested failed. What did you think caused it, and what did you do about it?
maturity around failure analysis and whether they treat failure as information rather than something to hide
What draws you to engine design specifically, versus another area of mechanical engineering?
genuine interest in propulsion and engines versus a generic internship application
Tell me about a time you had to teach yourself a tool or skill you'd never used before in order to finish something.
self-motivation and learning ability, since the role expects fast onboarding with limited hand-holding
Technical
Walk me through your experience with CAD software, especially Creo if you've used it, and how you'd approach learning it quickly if you haven't.
actual CAD fluency and honesty about gaps plus willingness to ramp up fast
Say you're given a component with a tolerance stack up problem where parts aren't fitting together consistently on the line. How would you go about figuring out where the error is coming from?
basic grasp of dimensional stack up and a logical troubleshooting approach, since this is named directly in the posting
What does a validation test plan need to include, in your view, before you'd feel confident running a test?
whether they understand the structure and purpose of test planning, not just running experiments blindly
Situational
If a supplier tells you a part failed a validation test but their own data looks fine, how would you handle that conversation?
diplomacy and technical confidence when working with outside vendors on a sensitive issue
How would you explain a technical result to someone outside engineering, like someone in manufacturing or quality, who needs to act on it but doesn't know the jargon?
technical report writing and communication skills called out explicitly in the posting
You're given a small piece of a bigger project and a deadline that's tight. How do you decide what to prioritize if you're not sure where it fits in the larger picture?
independence and judgment when working with incomplete context, since interns often get partial visibility into projects
