I recently met a wonderfully bright senior at an institution in Manhattan while conducting a workshop on presentation skills. During the breakout session, his peers were blown away by his confidence and the ease at which he presented his strengths and interests. Clearly they were envious.
At the end of the event I brought up some of the best presenters, as judged by their peers, so the entire audience could benefit. This gentleman was a unanimous choice by his group. Much to my surprise, his presentation, specifically crafted for a potential interview, would have never landed him the position.
He was surely eloquent and confident. However, he was all over the place and made it clear that his passions were many. Entrepreneurial spirit is wonderful, but a scary thing for a potential employer. Please don't forget that someone hiring you is looking for a commitment - someone they can hopefully grow with. They are already concerned with the figures that state a typical 20 something will have 5 jobs by the age of thirty. Please don't add to their concerns with your lack of focus.
