It is difficult to recognize a narcissist because he (or she) spends all of his time acting, protecting his ego by presenting to the world a false image of himself. Consequently he becomes a master of deceit. But it is extremely important to be able to recognize people whose behavior is detrimental to their organization's performance.
A narcissist is not capable of putting the organization's needs before his or her own needs.Ref
Researchers have found that a narcissist reacts much more emotionally than a non-narcissist, sometimes with "narcissistic rage" when his (or her) ego is threatened.
A narcissist is someone who is overtly or subtly arrogant, exhibitionistic, vain, manipulative, and greedy for admiration. Narcissistic rage, character assassination and projection are some of the overt ways in which the narcissist expresses himself.
Despite tending to be exhibitionistic, it is very rare to hear a narcissist brag or boast. Instead, he tends to 'drop' information in the form of an ostensibly ordinary matter-of-fact report, which appears to be intended to elicit admiration without asking for it. For example, rather than say, "I was so please to meet our CEO, Peter Smith", he will casually allude to "...lunch with Peter", in a way that induces a sense of distance and inferiority in the recipient of the information; again maintaining his sense of grandiosity.
Here are a few pointers that may help you identify one:
Their lack of empathy colours everything they do. They may say, "How are you?" when you meet, but they are working from memory. They are not interested in how you are.
Virtually all of their ideas or ways of behaving in a given situation are taken from others, people they know and perhaps think of as an authority (mirroring).
Their sense of self-importance and lack of empathy means that they will often interrupt the conversations of others.
They expect others to do the day-to-day chores as they feel too important to waste their time on common things.
Listen for the constant use of "I", "me" and "my" when they talk.
They very rarely talk about their inner life, for example their memories and dreams.
They feel that the rules at work don't apply to them.
They will always cheat whenever they think they can get away with it.
If you share workload with them expect to do the lion's share yourself.
They love to delegate work or projects, then interfere by micro-managing it. If it goes well, they take the credit, if it goes badly they blame the person they delegated it to.
There tends to be higher levels of stress with people who work with or interact with a narcissist, which in turn increases absenteeism and staff turnover.
They get impatient and restless when the topic of discussion is about someone else, and not about them.
