By now, we all know that you shouldn't just out-and-out lie on your resume. You shouldn't make up a university or a job experience; employers can easily find out about those. But what about taking a little bit of poetic license with your job descriptions? Like inflating the importance of a job you had?
Your goal as a resume embellisher is to make the interviewer think that you did something much more important than you did, without ever saying specifically what you did. This requires being a little vague to begin with -- which isn't in your favor even before the interview phase because employers don't want vague statements in resumes or cover letters; they want specific, concrete examples.
Still, many people do it. According to a 2008 CareerBuilder survey, 38 percent of employees had lied about their job responsibilities. But the consequences if you're caught can be pretty severe.
