Exactly my problem.. I had posted this question in the main MBA application forum but didn't get any responses. So, I posted it in this forum again and then I saw your post. How can careers such as musicians, chess player help solve multi disciplinary problems? Also, why would you care about solving multi-disciplinary problems if you are a musician or an athlete? If I pursue a completely different profession, say musician, I wouldn't go to business school. If I become a musician, my goal would be to entertain people. How can my ability to play musical instruments or perform in a concert contribute to solving multi-disciplinary problems?
I am confused.
I think I've got a better grasp on the question now that I'd had some time to think about it.
I think the ideal content for this question would be an extra-curricular activity that you have a real passion for. Something that you can relate your experience to when it comes to solving multi-disciplinary problems. For example, if you volunteered with Habitat for Humanity, you could say your alternate career would be a home builder. You could then talk about the leadership you needed to show when you volunteered.
As to skills useful in solving MD problems, think "soft" skills like communication, persuasion, organization, motivation, vision, innovation, etc.
You don't have to go for the grand slam. I think this question also tests your ability to relate your personal experiences to the "bigger picture". Going back to the Habitat for Humanity example: If you were working on a bathroom remodel and people were getting in each others way, maybe you organized the work so it was done more efficiently? That would fall under leadership and organization. Those are both skills that would be useful in solving MD problems.
I think you need to focus less on what the alternate career is and more on the day-to-day skills you show when you pursue it. For example, if you had a musical skill you could talk about the leadership you showed when you tried to organize practice sessions.
