Every year, I see resumes from students who try to stretch the truth in order to sound more desirable on paper. Resume inflation. This lack of honesty, when discovered, instantly disqualifies that person from further consideration. Corporate Recruiters are paid to screen people out, and the quickest and surest way a candidate is screened out is when a white lie (it is still a lie, white or black) or exaggeration is found.
Your resume is a reflection of who you are. Make sure yours reflects your very best.
A recent graduate attempted to show experience in a computer language by placing it on his resume. It generated calls, but it also generated rejection letters when it became apparent that he did not really have a foundational understanding of the language. Doors were shut (very hard, I might add) that could have otherwise been open to him.
Remember, the resume is not a work of fiction. While it should emphasize the positive, it should never emphasize what does not exist.
