I did the same thing, man oh man that was a bad call. I also graduated in December.

I worked on campus and once I graduated, I also had to say goodbye to any future paychecks from them.

Just last week (about 3 months after graduation) I was able to land a job in my field at a prestigious organization.

To those scared -- I HIGHLY recommend contacting a local temp agency or job recruiter (known as head hunters) and be sure to mention you have a degree, otherwise you'll be working a shitty assembly job. It's a 3 way win -- you get a job and experience, the employer gets a position filled and the head hunter gets money from the company that hired you.

A bit more general advice: Include keywords in your resume -- lots of them. Your resume gets thrown into a database that gets searched for keywords then read if queried, then forwarded to the hiring manager for approval if HR thinks you're a good candidate.

There are niche job posting sites -- you usually pick them out when you apply for jobs via monster/indeed/careerbuilder.

Anyone with a Biology degree, feel free to drop me a PM -- I've got plenty of science related niche posting sites.
