Purchasing Manager Question:

► What was the most important task you ever had?
► Tell me about your proudest achievement.
► What quality of yours or personal trait matters the most in your career?
► Which subjects did you enjoy during your qualifying degree?
► What attracted you to this company?

Have some good ones handy to mention. We recommend that you don't immediately respond to the question directly. A successful interviewee should give examples of past experiences when these skills came to use.
