What are the most important considerations to remember when proofreading a résumé, and how do you ensure a well written résumé?

What will be an ideal response?

Answer: Employers view your résumé as a concrete example of your attention to quality and detail. Your résumé doesn't need to be good or pretty good–it needs to be perfect. Although it may not seem fair, just one or two errors in a job application package are enough to doom a candidate's chances.
Your résumé is one of the most important documents you'll ever write, so don't rush or cut corners when it comes to proofreading. Check all headings and lists for clarity and parallelism, and be sure your grammar, spelling, and punctuation are correct. Double-check all dates, phone numbers, email addresses, and other essential data. Ask at least three other people to read it, too. As the creator of the material, you could stare at a mistake for weeks and not see it.
