To many job seekers, a resume is little more than a comprehensive list of work experience. However, just because it is work experience does not necessarily mean it belongs on your resume.
If you are applying for your first job, add as much work experience as you possibly can, it will show determination and work ethic. Though, if you are applying for a professional job in your mid-30s, the people reviewing your resume will not care where you worked when you were in high school.
Employers want to see information that is related to the position they are trying to fill. A detailed list of every job you have ever had can make it difficult for employers to see your relevant work experience and may unintentionally put up a red flag for hiring managers.
