Many people seem to neglect their resumes or think that they aren’t very important. Those people have never been recruiters before. Recruiters job is not to find reasons to say yes, but instead to find reasons to say no. Mistakes on a resume are an easy way for me to say no to a candidate. If you have misspellings, grammatical errors, unexplained holes in the years you worked, or a resume not targeted at the job you are applying for I will likely throw your application out and move on to the next candidate.
