Deadly Mistakes.
Since a single advertised position might bring from several hundred to over one thousand responses, even when filtered digitally, a recruiter has a large stack of responses to review. This means that her frame of mind is about "screening out" as many resumes as possible on the first pass so that she can spend more time analyzing the 10-20% that remain after the first quick scan. If you were a qualified candidate for the position, how would you feel if your resume got put in the reject pile because of a misspelling, or the organization was sloppy or inconsistent?

According to recent information from The Robert Half Organization a high number of otherwise competent candidates get rejected simply because the candidate has published a resume with avoidable mistakes.

A few of the most obvious mistakes: grammatical errors, knowing little about the company, their business, or the kind of people they hire, taking four pages to communicate two pages of information, complaining about earlier employers.

Action: Have your resume "double edited" before releasing it, by 1/ someone in your field and 2/ by someone who has a good eye for writing errors.
