Just skimmed this thread and wanted to add a few comments based on some general questions/assumptions I saw...
Do NOT go into public accounting for the travel experience. Yes, as an auditor they will send you pretty much wherever you are willing to go, but more often you'll have to go places you don't want to go. When you are travelling on their dime, they want to get the most out of their investment, so don't expect much leisure time, if any. You will get very familiar with the client's conference room, cafeteria (if available), and restrooms (most likely because you will want to sit on the toilet just to have some personal time to yourself). My favorite was getting sent to pick up dinner because I got to get out of there and see the outside world, albeit briefly.
In public accounting you are generally considered an expendable resource, of which the partners want to maximize utility. If you are fully utilized and willing to sacrifice your personal life, you become more valuable. There are unlimited amounts of work to be done, so you are never truly finished unless you decide you are done. There is nobody who is going to commend you for doing a great job or tell you to take a day off, only people who will see you as someone they can push more work on who will not say no. Think of the firm as a multiple layered prostitution ring, with a few pimps and a bunch of ****. Daddy wants as much as he can possibly get from you. You will excel if you keep daddy happy, bite your bottom lip, and serve your clients well. When you finally stop fighting it you can actually gain some pleasure from the experience. There are good days and bad ones, but my best days were the first and last to be completely honest. And I lasted 4 years... 2 in audit, 2 in tax.
If I could do it all again, I would look for an accounting job in an industry that I like right from the start. The big firms just made it so easy to find a job by coming on campus and basically throwing themselves at accounting majors, while many of my friends with other majors had zero prospects and many ended up moving back home with their parents after graduation.
