We tend to imagine “interesting” as a trait you either possess or do not. Some people have traveled farther, read stranger books, know obscure facts, or have the kind of job that makes a dinner table lean in.
But there is another form of interestingness: the ability to draw better material out of other people.
A person who asks a precise follow-up question changes a conversation. Instead of waiting for their turn to speak, they give the other person somewhere new to go.
Ask questions that cannot be answered by a résumé. What do you do? becomes What part of it do people misunderstand? Where are you from? becomes What do you miss that you cannot get here?
Curiosity without contribution can become an interview. Interesting conversation is reciprocal. Read things outside your job. Learn a ridiculous amount about one niche subject. Notice what you are noticing.
Being interesting is less about having impressive answers than making better conversation possible.
