When I have a short space for this question, I usually just write sentence after sentence of job titles and duration/time period to grasp my full timeline as a non trad. For me personally, I’d rather share everything I’ve done so they get the full picture and then if they like me, we can discuss the details of each during an interview lol. I’m too afraid of leaving things out and looking like I haven’t used my time wisely. For unheard of things, obv you should elaborate. But I don’t see the point forcing details of common activities like being a scribe or medical assistant for example or even volunteering activities that are well known (shelters, soup kitchens, tutoring, etc). It’s tricky bc of the “describe” but I would go with what will present your complete profile. Hope this gives you an idea on how to approach it!
