A resume should include your 3 to 4 most relevant and recent jobs if you’re using a one-page resume. If you have additional relevant experiences, you can list more jobs. Just make sure those jobs are within the last 10-15 years and fit comfortably on your resume.
If you’re a recent graduate, you can add internships and volunteer experience to fill your resume. If you’re an executive, you should list every job where you had a leadership role so the hiring manager can see your career progression.
