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.
In the short term, you should tweak your resume based on each job you apply to. For example, if one position you’re applying to seems to weigh a certain responsibility or focus over another, you should be sure your resume conveys your expertise in this area. At the same time, you should be updating your resume with your experience as it develops, adding any new skills you’ve learned, courses you’ve taken or awards you won.
