I started working in the ED at my local hospital only a week before I got accepted to school--honestly I have no idea why they hired me since I talked about med school in my interview with my manager. Anyway, I do patient registrations and insurance verification--it's kind of a lowly position but it's paying the bills and I get to talk to patients all day.
I do think that having this job will make me appreciated the rest of my coworkers in this type of position in the future. It's all about the teamwork, and they really do need me to do my job if they want to do theirs efficiently. Truth be told, I've been treated like crap by nurses (more often) and docs, but I'm just taking it with a grain of salt and telling myself it's good experience and only temporary. All in all the majority of the nurses and docs are super friendly/respectful and excited to talk with me about my future in med school though. Maybe that's a type of position you could look into also?
