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 class project or job where you had to work with a team to solve a hands-on technical problem. What was your role?
What they are checking: whether they can contribute meaningfully on a plant floor team rather than just in a classroom setting
Have you ever had to explain a technical idea to someone who didn't have your background, like an operator or a non-engineer? How did you adjust how you talked about it?
What they are checking: communication skill across different levels of an organization, which the posting explicitly calls out
Tell me about a time you had to manage a project mostly on your own, from start to finish, without someone checking in on you every step.
What they are checking: self-direction and ownership, since the role explicitly involves owning projects independently
Describe a situation where you disagreed with a teammate or supervisor about the right way to do something. How did it get resolved?
What they are checking: ability to manage contentious situations productively, which the job description names directly
Why Mercury Marine, and why manufacturing engineering specifically, over other kinds of engineering work?
What they are checking: genuine interest in the industry and the discipline versus applying broadly for any co-op
What would you do
Say you're on the floor and a production line stops because of a part that isn't fitting correctly. Supervisors and operators are waiting on you. What do you do first?
What they are checking: whether they can stay calm and prioritize under time pressure with people watching
If you found a way to cut cost on a part but it meant asking a vendor to change how they do something they've done for years, how would you bring that up with them?
What they are checking: comfort with vendor-facing communication and handling pushback diplomatically
If a design review turns up a part that's hard to manufacture at volume, what questions would you want answered before recommending a change?
What they are checking: whether they think about manufacturability and design tradeoffs, not just theoretical engineering
This co-op runs a full six months, forty hours a week, away from your normal school schedule. How are you thinking about balancing that with your program and your life?
What they are checking: realistic understanding of the commitment and logistics involved
About the work
Walk me through how you'd approach evaluating production data to figure out why a manufacturing process isn't meeting its cost or quality target.
What they are checking: basic grasp of data-driven root cause analysis, appropriate for someone early in an engineering program
What do you know about how outboard or sterndrive engines get assembled, and what kinds of manufacturing processes do you think are involved?
What they are checking: genuine curiosity and preparation about the specific product, not just generic engineering knowledge
What coursework or lab experience have you had with process improvement, lean manufacturing, or cost reduction studies?
What they are checking: whether their academic background actually lines up with the process improvement work described in the posting
What tools have you used for data analysis or statistics, like Excel, Minitab, or something similar, and how have you used them?
What they are checking: concrete familiarity with tools they'd need for evaluating test and production data
