Which resume type should you use for your job search? That depends on what you are trying to accomplish. The goal of any resume is to show a hiring manager the applicants strengths, skills, and experience in as short a time as possible. According to one study, recruiters spend as little as six seconds reviewing a resume before moving on to the next, so it is in your best interests to put your finest qualities and accomplishments in a prominent position on the page.
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.
