Social engineering is the act of manipulating people into performing actions or divulging confidential information, rather than by breaking in or using hacking techniques. While similar to a confidence trick or simple fraud, the term typically applies to trickery or deception for the purpose of information gathering, fraud, or computer system access so in most cases the attacker never comes face-to-face with the victim.
