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 had to figure something out with limited direction or without a clear answer available.
What they are checking: comfort with the ambiguity of a co-op role where they'll be expected to work independently early on
Describe a group project where you had to coordinate with people outside your immediate team, like another department or an outside partner.
What they are checking: readiness to collaborate across engineering and procurement functions the role explicitly touches
Tell me about a time you had to learn a new system or process quickly with not much training.
What they are checking: how they handle the fast onboarding typical of a co-op with no formal ramp time
Tell me about a time you gave feedback or pushed for a change and someone more senior than you didn't want to hear it.
What they are checking: whether they can use influence rather than authority, since this role has no direct reports and works through persuasion
What made you choose to apply for a co-op instead of just an internship, and what are you hoping to get out of a six-month term here?
What they are checking: genuine motivation and whether the length and structure of the commitment actually fits their goals
What would you do
Say you're auditing a supplier's manufacturing line and you spot a process step that isn't being followed the way their control plan says. What do you do next?
What they are checking: whether they know a structured audit-to-corrective-action workflow rather than just flagging a problem and walking away
A supplier pushes back on your finding and insists their process is fine. How do you handle that conversation?
What they are checking: ability to hold a position professionally with someone more experienced and often external to the company
You're managing a supplier relationship for one commodity and two priorities collide, a new supplier needs technical qualification while an existing supplier has a corrective action overdue. How do you decide where your time goes?
What they are checking: prioritization skills when given real ownership without a manager directing every task
How would you explain a technical quality issue to someone in procurement who doesn't have an engineering background?
What they are checking: communication skills across functions with different levels of technical fluency
About the work
Walk me through what PPAP is and why a supplier would need to submit one before we approve a part.
What they are checking: whether the candidate has real coursework or exposure to production part approval process versus just having heard the term
What quality tools or methods have you used in school or a past job, things like FMEA, root cause analysis, or SPC?
What they are checking: actual hands-on exposure to the specific tools this team leans on daily
If you found a defect during a sorting or containment activity at a supplier, how would you decide whether it's a supplier issue or something on Mercury's end?
What they are checking: basic understanding of root cause thinking and not jumping to conclusions
What coursework or projects have given you exposure to manufacturing processes, like machining, assembly, or materials?
What they are checking: whether their mechanical or manufacturing engineering background actually connects to real production environments
