Thanks for your comments. I'll comment on joining the legal profession at the entry level and on public interest law.
How legal hiring works at big law schools is this: you go through your first year and get your grades. At the beginning of your second year, you interview with big firms. You hopefully get an offer to work at one summer of your second year. You do well that summer and hopefully get an offer.
This is the primary hiring pipeline for all big firms. A much smaller pipeline is lateraling over from another big firm after you've worked there a few years, but still, you need get through this pipeline at some firm.
If you miss this window, you're basically finished in terms of prospects at a big firm. A couple of people manage to pick up a job their third year but its pretty hard (I tried but failed).
It's a really weird system I know. But yeah, there's no way for me to go to a big firm and say "I'll work for free if you give me a shot."
I could do that with much smaller firms but then instead of 160k market salary + high-level, interesting legal work being the end game its more like 40k and much less interesting work.
As to public interest orgs like EFF, if I work at some place like that, then between the federal government program and my school's program I can get some assistance and, after 10 years, get my debt forgiven. I'm looking into this seriously and this is my "backup" plan. 10 years is a long haul for something I'm not too excited about (see post) and at a very low salary, though.
