Behavioral
Walk me through a global sourcing strategy you built for a commodity category, from initial analysis to final execution.
whether the candidate has actually run a full strategic sourcing cycle rather than just executing tactical buys
Describe a time you had to reduce total cost of ownership on a category without hurting quality or service levels. What levers did you pull?
whether they think beyond unit price into TCO components like logistics, defects, and lead time
Tell me about a time you found a supply risk before it became a real problem. What tipped you off, and what did you do?
proactive risk mitigation instincts versus reactive firefighting
Tell me about a negotiation where you had to hold your ground against a supplier who had real leverage over you. What happened?
negotiation skill under a power imbalance rather than in easy wins
Tell me about a time a supplier relationship went from adversarial to collaborative. What did you personally do to shift it?
relationship management skill and self-awareness about their own role in supplier dynamics
Technical
Tell me about the plastics or MRO categories you have managed. How did you approach supply base rationalization for one of them?
direct category expertise and whether they know the specific dynamics of plastics or MRO supply markets
How do you structure a supplier quarterly business review, and what do you do when a supplier consistently underperforms on the metrics you set?
whether they have real supplier performance management discipline versus just holding meetings
What is your experience being an SAP super user, and what kinds of issues did you end up resolving for other users in your function?
depth of actual SAP ownership versus casual end-user experience
Describe a lean or Six Sigma project you led that changed how a supply chain or category was managed. What was the measurable result?
whether continuous improvement claims translate into concrete, measurable outcomes
How do you benchmark supplier costs and capabilities globally, and what sources or methods do you actually rely on?
whether their benchmarking process is rigorous or just anecdotal supplier comparisons
Situational
Say a key plastics supplier tells you they need a 12 percent price increase due to resin costs, but your budget has no room for that. How do you handle the negotiation?
negotiation tactics and whether they understand cost driver transparency in commodity-linked materials
One of your suppliers is your sole source for a critical plastic component and just had a plant fire. Walk me through your first 48 hours.
crisis management and whether they have a real framework for single-source risk
You're leading a cross-functional team on a material cost reduction initiative, but engineering and quality disagree on which supplier change is acceptable. How do you move this forward?
cross-functional leadership and ability to resolve competing priorities without formal authority over the team
This role requires about 30 percent international travel. What has your experience been managing suppliers or negotiations in person overseas versus remotely?
