Ask HN: How exactly do you get a job interview?

I've been sending my resume to websites and recruiters all day long. The recruiters will call back but always mention how unqualified I am. The company jobs websites never call back.

I hear rumors of "Fizz Buzz" questions but never been asked because nobody really calls me back. I also hear rumors about how there are so many unqualified candidates there are out there and judging from what the recruiters are saying, I probably am unqualified as well but I'm trying not to be unqualified but no matter how much I learn, it feels like I'm still unqualified from the responses I get.

What exactly does it take to become qualified to just get a job interview? What do you need to do to become qualified for a job? How do you go from being incompetent to competent?
