In theory and in reality a wolf in sheep's clothing is a key concern for employers and recruiters to be wary of in the selection process.   

It begs the question, "Which candidate are you most comfortable with in assessing for employment consideration—the raw and somewhat transparent candidate, or the highly polished, highly confident one?”  On the one hand, the raw/transparent candidate may not impress as much as the highly polished interviewee.  But under all that gloss and glow may be a talker and not a doer--or worse.

Your take?
