This may surprise you then, but the vast majority of companies aren't called "firms." If you want to know have I worked, the answer would be yes.
In addition, I have access to reams of hard data on hiring by virtue of being a law student that lets me comment much more intelligently on legal hiring than you can on accounting hiring.
You are right. The fact that I've interviewed people and worked in Big Four for a few years means I know less about accounting hiring than you know about legal hiring. I'm sure you learned much more from your reams of mostly-publicly available data than I learned from my statistics that are complimented by work in the field, regular meetings with partners, and building staffing models for my office.
EDIT - Are we talking about hiring data? Or the pros and cons of choosing a career as an accountant or lawyer? I'd like to know. Oh, and I'm posting real shit: viewtopic.php?f=2&t=105891&p=4009002#p4009002. What are you adding here exactly other than telling me you don't like me, basically.
