Generally, a resume is much shorter in length compared to a CV, usually limited to one page. It is meant to be a very brief synopsis of your career and education history. Resumes should focus on measurable accomplishments rather than soft skills or listed responsibilities. Like a CV, resumes need to be updated, but those updates should be made form specific job to which you are applying.
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.
