With this question, the interviewer is not so much interested in examples of your success – he or she wants to know what makes you tick. Keep your answers short, general and to the point. Using your professional experience, personalise and use value keys from your personal, professional and business profiles. For example: I attribute my success to three reasons: I’ve always received support from my colleagues, which encourages me to be cooperative and look at my specific job in terms of what we as a department are trying to achieve. That gives me great pride in my work and its contribution to the department’s efforts, which is the second factor. Finally, I find that every job has its problems, and while there’s always a costly solution. There’s usually an economical one as well, whether it is in terms of time or money. Then give an example of your experience that illustrates these points.
