Second "yesterday." How is OP so casual about this? $300k at 10% interest is crippling for a new grad, especially a slightly older one. Just the interest is $30k a year. Every year! Just to tread water! This is a debt emergency of staggering proportions.

If you're a junior, you should already have marketable skills. You need to start earning something ASAP, even if it's applying to every scholarship under the sun. I don't know why/how you're taking for granted that you'll even be hirable in a big tech company right out of school, especially making enough to cover an extra $30k+ in loan payments every year.
