1. There are a lot of interruptions from them
Narcissists who engage in conversation will jump into the conversation while someone is in the middle of speaking, says Behary. “At first listen, it can sound like they’re being helpful or sharing a resource, but it quickly becomes clear that this conversation is no longer about you—it’s about them,” she says.
2. They never stop talking
Since narcissists constantly seek approval and favor from their audience, Behary says their constant talking will sound more like a lecture than a conversation. “There’s so much showing off and wanting to appear to be very smart, special, knowledgeable, and intuitive,” she explains.
This is different from a chatty and extroverted person, who would likely be aware of, and even acknowledge, that they’re talking a lot, “whereas conversational narcissists are not even aware that they’ve hijacked the conversation and made it all about them,” Behary says.
3. Overbearing during a conversation
4. They have a complex of unwarranted superiority
5. They use a lot of filler words
