Talk about a time you had to train someone in something they have no experience in.

There are those who strive to contribute to the vision and the greater success of a team. Then there are those who strive to develop themselves, driven by their own ambitions to accomplish their personal and professional goals. There's nothing wrong with ambitiously trying to climb the ladder. But a person who prioritizes their own goals above others, or that of the team, can undermine their own efforts towards success. Prioritizing the ultimate success of the team displays big-picture thinking. Investing in the development of your coworkers, and driving positive change towards the greater success of the team is an investment in one's own development. By contributing to the greater success of the company and the team, you contribute to your individual success and development. The scope of your vision, the big picture versus a more narrow short-term view, is what the interviewer is truly trying to assess.
