There are some things that don’t belong on a resume for a job. What you exclude is just as important as what you include. Ideally, your resume should reflect experience that is relevant to the job you are applying to, and typically no more than ten to fifteen years in the past. Since your resume should, if possible, be no longer than one or two pages, you may need to nix certain items.
A resume is the representation of your professional self. It is a concise compilation of your educational and professional experience, as well as the skills that make you desirable for the workforce. It is what you use to sell your merit and skills to potential employers.
