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 leading a technical discussion with a supplier where your own engineering team and the supplier disagreed.
What they are checking: Sitting between design and supply, which is the whole job.
This is in Mount Prospect asking for five to seven years and preferring mechanical, electrical or industrial engineering. What would you want to know about the project pipeline before starting?
What they are checking: That they ask what they will actually be working on.
What would you do
This role ensures cost, qualification and delivery of components against a project design book. When those three conflict on a part, how do you decide?
What they are checking: The central tradeoff of project purchasing.
You coordinate part approvals by getting inspection reports and test reports from suppliers. What do you do when a supplier's documentation does not match what they shipped?
What they are checking: Handling a quality documentation gap before it reaches production.
You manage several projects at once with different parts. How do you decide which one gets your attention in a given week?
What they are checking: Prioritization across concurrent programs.
You own the purchasing portion of budgets and tooling expenses. How do you handle a tooling quote that comes in well above what was planned?
What they are checking: Managing a cost overrun rather than simply reporting it.
You work with a global purchasing team under Bosch procedures. How do you push a project along when a decision sits with a colleague in another region?
What they are checking: Working a global matrix with time zone and authority gaps.
About the work
You would run supplier selection for new parts using competitive pricing analysis. What do you look at besides the quoted price?
What they are checking: Total cost thinking — tooling, capacity, quality history, logistics.
The commodities named here run from plastic and machined parts to die cast, electrical, electronics and powder metal. Which of those do you know best, and how do you get up to speed on one you do not?
What they are checking: Honest breadth, and a method for learning a new commodity.
A part is qualified and then the design changes late. What happens next?
What they are checking: Understanding of requalification cost and schedule impact.
