Yahoo! Finance is carrying a great article on resume killers that can put your resume in the trash instead of in the interview pile. From the article:
There Are No Numbers. One of the worst things you can do on a resume is be vague. Don’t just list your accomplishments in a general way — have the quantitative data to back it up. If you exceeded a goal, by how much did you exceed it? If you created and distributed company performance reports, how many did you do? Adding numbers concretizes your accomplishments and paints a better picture of what you actually did.
Also, make sure you are answering the “how” question. If you completed five projects this year instead of the expected four, how did you do it?
