Tell me about a time a key supplier let you down. How did you handle it and what changed afterwards?

What the interviewer is looking for

• This question tests vendor & supplier management. Sets clear expectations with suppliers, tracks performance, negotiates and has backup options.
• What to bring out: Contained the immediate impact, communicated with the supplier and customers, held them accountable and added backup suppliers or better monitoring.
• Expect a follow-up like: How do you decide whether to keep or replace a supplier?

Another way it may be asked: Think of a time a supplier missed a delivery or sent bad materials. What did you do?

A structure to follow: STAR, with the weight on Action and Result

1. Step 1

   Situation

   One or two sentences: where, when and what was at stake. Pick a real example you were close to.

2. Step 2

   Task

   What you personally were responsible for. Say "I", not only "we", so the vendor & supplier management you showed is visible.

3. Step 3

   Action

   The two or three things you did and why you chose them over the alternatives. This should be about half your answer.

4. Step 4

   Result

   What changed, in your own measure of it, and what you would do differently. Only use numbers you can stand behind.

This is guidance on shape, not a script. Use your own real experience and facts; never invent details to fill a gap. See the STAR guide and answer frameworks.

Common slips

• Describing what the team did without saying what you did.
• Choosing an example with no clear outcome, or one you cannot answer detailed questions about.
• Ending on the action and skipping the result and what you learned.

How to practise it

Write two bullet points for each STAR letter, then say the answer aloud in about two minutes.
