Check the facts first
Confirm names, company titles, dates, links, email address, phone number, and the role you are applying for. These items are easy to overlook because your attention is usually on the wording, but they are the details a reader may use immediately.
If you tailored the resume, make sure a previous employer or job title has not remained in the summary, filename, or cover letter by mistake.
Read it in a different format
Export the document to PDF and read it there. A new format slows you down enough to notice spacing, awkward page breaks, missing bullets, and repeated words that felt invisible in the editor.
Read from the bottom up for a spelling pass, or ask someone you trust to look at it. A fresh reader is better at noticing what your eyes have learned to skip.
Check whether the page can be skimmed
Before you send it, give yourself ten seconds. Can you find the target role, the most relevant skills, the recent experience, and a few concrete accomplishments? If not, the issue may be order or density rather than grammar.
Proofreading is also a professionalism check: a clean, consistent document makes it easier for the reader to focus on your qualifications.
