Job roles on a resume for a junior jobseekers

I always see blogs and posts on how to make your resume stand out from the rest by including achievements and significant contributions in your previous job/s (increased sales by X%, managed a team of X people). I'm wondering how that can be applied for junior jobseekers with 3 years or less of experience under their belts. Most junior positions don't really involve significant roles to showcase on your resume. It's mostly just doing whatever your superior asks of you. Any suggestions?

Thanks!
