You just observed this applicant in a sales situation, since he was trying to sell his labor to you. More than likely, this is how he will present himself to your customers if you bring him on board.

As part of your decision-making, be sure to carefully review his work history and tack record. This is a strong predictor of his future sales success.
The fact that some of your associates liked this individual is not surprising. He is friendly, communicative, and has some great stories. However, liking an applicant is very different from determining if an applicant is a good match for a particular job. Most applicants are likable, but that does not mean they are hirable.
