Amen, sister (or brother)!

Unfortunately, I can't enlighten you about why people use such meaningless jargon and clichés in their résumés, cover letters, or telephone calls. Is there some wicked person, or some ill-conceived how-to book, recommending this to people looking for work?

Aside from the pointlessness of the phrases, job seekers should keep in mind that while a recruiter might do keyword searches for words like "RRT," or "paramedic," or "transcriptionist," or "Registered Nurse," or "ICU," no recruiter is going to do a keyword search for "paradigm shifters," or "people persons," or "outside the box thinkers."
