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 got a struggling supplier to zero defects or close to it. What changed?
What they are checking: Whether they can drive real improvement at a supplier, not just send corrective action requests.
Tell me about a time you had to hold firm with a supplier on a quality issue when Purchasing wanted to keep the peace.
What they are checking: Whether they can protect quality while keeping internal relationships with buyers working.
How would you measure whether your work is improving first-time-through and reducing line downtime?
What they are checking: Whether they connect supplier quality work to plant results like FTT, scrap and downtime.
What would you do
A supplier sends an 8D that says the root cause was operator error. How do you respond?
What they are checking: Whether they push suppliers past weak root causes to find the system failure that let the error happen.
Raw material is in spec on paper but running poorly on the line. How would you figure out what's going on?
What they are checking: Whether they look beyond the spec sheet to find the hidden variable that affects how material performs in production.
Material is sitting in the hold area and production needs it. How do you reach a disposition quickly without taking a risk?
What they are checking: Whether they can balance line needs against quality risk with sorting, deviations or rework done properly.
A supplier submits an eSCR for a process change during a busy launch. How do you evaluate it?
What they are checking: Whether they understand that unmanaged supplier changes are a top cause of quality escapes.
About the work
Walk me through the PPAP elements you would look at most closely for a new part from a new supplier.
What they are checking: Whether they know which PPAP elements really prove a supplier can make good parts, not just complete paperwork.
How do you use supplier PPM and incident data to decide where to spend your time?
What they are checking: Whether they prioritize by risk and impact instead of reacting to whichever supplier complained loudest.
What does IATF 16949 require for supplier quality management, and how would you build procedures to meet it?
What they are checking: Whether they know the standard well enough to write procedures that pass audits and actually work.
How do you review a supplier's PFMEA and control plan to see if they're realistic?
What they are checking: Whether they can spot shallow documents that list controls the supplier does not truly use.
