Thanks for everyone's advice. Will accepting offer from big 4 starting Sept 2009 (audit for financial industry). Will get my CA and probably move on to tax or a mid-size.
Congrats on your new job. Sounds like it will be a lot of work, but while you're young and single you can work hard and play hard too, just make sure you do both.
Don't get caught up in an expensive lifestyle, and you will have many options to choose from in a few years. Good luck!
