Am I the only one with adhd who's good at and enjoys networking? Most of it is just asking specific questions based on prior information you've been given by the other person.
Really important is identifying a topic the other is passionate about, maybe it's not even work related, but a hobby or a travel experience they've had. Then you get them to "teach" you about it by asking them to elaborate and maybe even explain specific parts of their hobby, and voila you've succeeded in networking.
People are passionate about their skills and hobbies, and most love to elaborate and explain the specifics of it, especially when they usually don't get to do it.
Remember those "Joe is forcing us to see his travel pictures" joke? This is basically that but you're actually interested in the pictures. Listening to someone being passionate about something is a lot more fun than others lead you to believe, give it a try, it's basically nt infodumping.
