Commodity Manager Interview Questions: 50 Real Ones With Scored Answers

I have hired commodity managers for metals, electronics and battery categories, and the interview is different from a GSM loop. The questions below test whether you own a market, a supplier portfolio and a three-year plan, and each one has the answer that gets a 9 from me and the reason a 5 falls short.

How Commodity and Category Manager answers are scored

Every model answer in this track is graded on five criteria. A 7 is a solid hire. A 9 gets the offer.
