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 job where you had to work with a team to solve a hands-on technical problem. What was your role?

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?

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.

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?

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?

genuine interest in the industry and the discipline versus applying broadly for any co-op

Technical

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.

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?

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?

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?

concrete familiarity with tools they'd need for evaluating test and production data

Situational

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?

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?

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?

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?

realistic understanding of the commitment and logistics involved
