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.
Once you’ve decided on a resume type, it’s time to start writing your resume. You don’t have to start from scratch. First, review examples of the resume type you’ve selected. Then, choose a template which you can copy and paste into a document, and then fill in with your own work history.
