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.
References. It is assumed that you have references if you have previous employment history. It is not at all necessary to include “references available upon request”, adding this is actually a potential deterrent. Potential employers will ask you for your references later on in the interview process if they see fit. Of course, if references are asked for within the application process, provide them - just not on your resume.
