Work experience in medical field? (premed changing fields) Help.

Hi all!

I am going to graduate with a 3.0 cumulative GPA and a science bachelors degree. I am 27 years old, been in school a while, got held back 1 year in HS (wasn't serious about school, graduated with sub-2.0 GPA I believe, completely turned my life around after wards), took 1 year off after HS basically. I have SOME (not enough to justify it all) reasons for my poor GPA (death of someone close, had big surgery, some mental/emotional issues too).

I am an older applicant (or future applicant) who was premed for a while. I realized that medical school wasn't the route for me, my heart wasn't in it, and recent events made it even more clear.

My goal is a top 20 b-school. I take the GMAT in the fall. I decided on the path of the MBA based on advice from some of my friends and mentors, including someone who worked for a large hedge fund and a friend who is in Stanford b-school currently.

I have a lot of volunteer work and work with nonprofit organizations. I've been on several medical missions trips to different countries, etc., but that's obviously unpaid, in-fact, I paid to do it lol. I do have the option of doing a 1-year long internship for a nonprofit. Started an organization on campus for human rights, and held a national position with a human rights organization. The 1-year position was stipended, not sure if that counts as work at all.

The issue is that my degrees are designed to be stepping stone degrees into professional medical programs, and they are VERY useless career wise when used alone.

I've worked 6 months as a science and math tutor at my college, and 6 months at Abercrombie as a model (lol). Does that count as 1 year work experience? I know the second one sounds like a joke job, but I liked it and it demonstrates being sociable, which is less common among people from my major.

How much does part-time work experience count? Like if I worked several years part-time? I really can't find the answer to this, everywhere says b-schools desire full-time, but that you can also list part-time.

Should I get an MPH (masters in public health) or an MS in a hard science (like biomed or biotech or biomed engineering) and work a few years after that? This would take 2 more years. Even then, I would also mostly be working in a medically related field. But at least it wouldn't be an entry-level job. But it's still not a business-y related field.

Getting a second BS in something business related to get a job for a few years? This would take 2 years though.

Or what about getting an MBA from a lower ranked school, working a few years, and then applying to a higher ranked school for a second MBA? This one sounds like a bad choice.

Does work in the medical field count towards hours? Like working as a medical assistant, an EMT, or a scribe? None of these are managerial, or even in typical business settings. I'll be an EMT in a month or 2. I could easily become a scribe or a medical assistant.

I also don't know ANY traditional business/managerial positions that I am even qualified for with my degrees and background, so what if I end up working in some low end job like at Publix or something?

Or working as a personal trainer at my university's gym? I'm qualified for it.

Does unpaid work in a research lab count for anything? It would be 10-20 hours a week for 2 years if I decided to do that. It would be the exact same work that somebody being paid in a lab would do, it would just be unpaid.

Thanks ya'll!
