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.
Not even professional proofreaders can easily proofread their own work. Once you’ve made a typo, it’s hard to catch it yourself. For that reason, it’s a good idea to have one or two trusted friends take a look at your resume before you send it in for consideration. Use this resume proofreading checklist first, then ask someone else to give it a final review to be sure it’s perfect before you click send or upload to apply for a job.
