I’ll start out by saying I don’t have a journalism background. I do, on the other hand, have a non science background. My advice would be to not spin it to fit into medicine if it doesn’t. Just talk about the experience in the context of how you contributed to it and how it affected you. What did you learn from that? What drew you to journalism?
Having different life experience is interesting and it will set you apart. Don’t try to fit your experience into a typical pre-med box. Schools are always looking for diversity, and this is actually great experience to answer the very common secondary question, “what diversity do you bring?”
