worked for me 😎 any experience will work, i think, so long as you explain how it's helped you learn some things about the realities of working as a doctor, or other such aspect. in my interviews, whenever it was brought up i talked about how it exposed me a little bit to the business side of medicine (esp. since the doctor i worked for retired and a younger doctor took over, so i got to see how the process of setting up a private practice, initial issues w/ insurance payments, setting up hospital affiliations, etc.), and also how it helped shaped my ideal doctor-staff relationship, doctor-patient relationship, good clinical environment, etc. i also talked about things that i genuinely liked - the older doctor was an internist, and so most of his patients have been going to him for years (some for 20 more), and sometimes sees whole families, which really made an impression on me and kind of pushed me to pursue internal medicine (at this point, anyway).
no matter how mundane you think it is, you're still getting experience in some aspect of healthcare. i'm sure if you reflect on it you'll find that you might learn some useful things 🙂
