Ask HN: How does an average CS graduate get a job?

I graduated with a CS degree, May 2015. No one in my entire family tree has ever graduated high school, so I've never had any encouragement or mentoring for CS. I ended up in a very average university: is not in top 100 of USNews. It's top 20 in Northeast.

In the school's job fairs, we get only local, unknown companies (like 3 of them). Problem is I don't live locally there, and they only hire locals and don't assist with relocation. I've applied elsewhere, but yeah... I'm unemployed after 5 months.

I've had my resume checked by multiple sources, and no one's had any problem with it. My non-school projects consist of websites. They're not exciting with no "xTreme-Framework-of-the-month", but I'm working on updating and integrating new features. I've also volunteered my programming skills and worked for an unpaid internship. I also have some related extracurricular.

Clarification: I have received many phone calls from unknown companies; zero on-sites. The problem is I can't get past the phone calls since they always ask me exclusive, tricky questions about their stack. I never get any algorithm or data structure questions like I hear in other threads.

My big problem is since no one in my family has an education and sees the CS degree as "a worthless piece of paper", they don't want my sister to go to university.

So, I really don't know how to find a job. I've tried the blackhole websites (e.g., dice.com); multiple 3rd party recruiters; school's job board (at this second, literally only has one position posted for software engineer); my neighbors and family's friends. No luck.
