And in no setting is it more critical than the job interview. Employers closely assess and judge candidates on their level of “enthusiasm” for an opportunity—and are unforgiving when a deficiency exists. So regardless of how qualified a candidate may be, a move forward can be won … or lost on this single expression. Given this reality, it is critical to tend to this aspect of your interview prep and overall career development. But some professionals are uncomfortable in this pursuit because they're not quite sure how to do so without being unnatural.

So how does one successfully project enthusiasm without being phony or awkward?

Understanding your general demeanor is a good starting point. Are you laid back? Intense? Jolly? Ask a friend or colleague for feedback on your manner and see where you fall on the enthusiasm meter. Next, it's helpful to appreciate what “enthusiasm” really means so you know what to aim for. To an employer, it means that you are happy to be there—alert, actively engaged, curious, knowledgeable, energetic, knowledgeable about their organization, upbeat …and you can carry a conversation. It also manifests itself in a firm handshake, excellent eye contact and a smile.
