To find out if your resume sells, take the document in hand and see if it answers the following:
 
What have you done on the job that distinguishes you from others in your field?

What projects or teams did you lead, or innovative concepts did you introduce, that had the most positive results on the company?
 
Have your accomplishments been quantified in detail versus just listed briefly? Are they tangible, bottom-line benefits from the employer's perspective?

How will your unique work style benefit a potential employer? How has your style fueled your accomplishments with previous employers?
 
Does the document include up-to-date language and the buzzwords hiring decision-makers are looking for?
 
Does the resume read like a marketing document that SELLS you, rather than a narrative of your work history? And a final checklist

Do you use numerals instead of spelling out numbers, to make the quantifiable accomplishments stand out?

Have you used a personal e-mail address and not your employer's? (e.g., Yahoo!, AOL, Hotmail versus your at-work account)

Is your resume easy to read, with all contact information and employment history basics readily visible? (e.g. name of company, title, dates of employment)
 
Have you proofread your resume at least twice and had another person review it for spelling errors, typing mistakes, incorrect dates, etc.?
