They'd see you as a nontraditional applicant. Like GoBruins said, they'd ideally want to see some sort of progression within whatever you're doing - whether it's larger projects, managing volunteers, etc. But keep in mind that whatever you pick, you have to explain how it ties into your longer term goals.
Are you a recent graduate or have you worked before? If you've worked before, you could tie that experience in as well!
Also, I'm sure you know this, but in your essays, I'd choose positive reasons for why you chose whatever career you did. And avoid any traditional-corporate-WE-bashing. Since 80% of bschool students have the more traditional work experience, and likely will be the students in the admissions office reading your app, you want them to feel intrigued and not alienated by your application. You want them to want you as a potential classmate.
