I'm interested in a career in academia, first and foremost -- but if that doesn't work out, I'm probably interested most in mid- to large-size firms, at least initially (big pay, big experience), with the outside possibility of hanging my own shingle later on (unless the possibility of partner looks promising).
If the academia thing pans out, then the areas I'm most interested in (academically) are international/comparative law, jurisprudence and legal theory (including Critical Legal Studies), law & religion, and some aspects of property law.
If I go into practice, then I'm pretty open to practicing in any area at that mid- to large-size firm -- whatever work they give me, and whatever catches my fancy at the moment. I have very little interest in criminal law, though. Prosecution doesn't pay anything, and defense carries too many moral dilemmas.
