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 time you worked on a team project in school or a past job where people had different opinions about how to solve a problem. What did you do?
What they are checking: whether the candidate can build working relationships across different roles, since the job requires daily interaction with supervisors, technicians, and hourly employees
Describe a time you had to collect and organize a messy set of data, maybe for a class project or job, and figure out what it was telling you.
What they are checking: comfort working with real, imperfect data rather than clean textbook datasets
Tell me about a time an authority figure, like a professor or manager, gave you feedback that stung a little. How did you handle it?
What they are checking: coachability, since the posting emphasizes ongoing feedback and performance reviews during the co-op
Tell me about a project you owned from start to finish, in school or work, where you had to manage your own timeline without much oversight.
What they are checking: readiness to independently own assigned projects, as the posting specifically calls out
Why are you interested in quality engineering specifically, rather than another engineering track, and why Mercury Marine's manufacturing environment?
What they are checking: genuine motivation and whether the candidate understands what this specific role involves versus a generic engineering internship
What would you do
Walk me through how you would figure out the root cause of a defect if a customer reported a problem with an engine part but the manufacturing floor said everything looked fine.
What they are checking: basic grasp of root cause analysis and whether the candidate defaults to blame or to investigation
If you noticed a process on the production floor that seemed risky or likely to cause a defect down the line, but nobody had raised it yet, what would you do?
What they are checking: initiative and willingness to speak up as a co-op without formal authority
Imagine a production supervisor pushes back when you ask for time or data to investigate a quality issue because it will slow down their line. How do you handle that conversation?
What they are checking: ability to hold ground diplomatically with people who have more plant experience and different priorities
You are told you can only work full time from January through August, or May through December. Walk me through your schedule and how you would make sure you meet the full 40-hour weeks and the co-op program requirements at your university.
What they are checking: logistical seriousness about the commitment and clarity on academic co-op program enrollment
About the work
What statistics have you used in coursework, like F-tests or distribution analysis, and can you give an example of a problem you applied them to?
What they are checking: whether the stated statistics background is real and applied, not just a class name on a transcript
Have you ever used gauges or measurement instruments in a lab or job setting? Tell me what you were measuring and how you made sure your readings were accurate.
What they are checking: any hands-on exposure to measurement and quality control tools versus purely classroom knowledge
How comfortable are you with Excel beyond basic formulas, things like pivot tables or data analysis tools? Give an example of something you built or analyzed.
What they are checking: whether 'advanced Excel skills' claimed on the resume hold up to specifics
What do you know about continuous improvement tools like Six Sigma, 5S, or root cause methods such as fishbone diagrams or the five whys?
What they are checking: baseline familiarity with the quality methodology vocabulary the job expects them to apply
