I've read scorpios are intense and intuitive to the point they can read your mind? lol. What are some signs he's interested/wants to get to know a girl? (assuming they Haven't gone out yet or barely talked)
Yep makes sense. People born on an arbitrary range of dates of a calender year have superhuman abilities.
Don't worry about the scorpio or whatever nonsense. Without talking to the guy the one obvious sign that he is interested is if he seems to be looking at you a lot. Of course this doesn't guarantee anything, but it's usually a sign that he's attracted to you. Guys won't stare too long or often at girls they don't find attractive.
