If you are using Word 2007, then you should be careful about what format you use to send out your resume.  Consider Mike’s story.

Mike is a very successful sales executive who truly has an impressive background. After 30 days of submitting his resume for well-matched jobs, he was getting no responses and contacted us. We quickly realized he was sending his resume out in Word 2007’s .docx format which many companies do not support, so we showed him how to change the default settings to save documents in an earlier version.  The result: within 1 week he was getting calls for interviews.
