The best auditors get excited by math and aren't fazed by the thought of staring at numbers all day. While they’re staring, auditors are reviewing accountants’ work by looking at financial documentation, checking for errors, and making sure that all necessary laws are being followed. Since they're in high demand, auditors have quite a bit of career flexibility. You could find yourself working for the government, a financial firm, as a university professor, or as the head of your own practice. These numbers gurus might get a geeky rep, but most people don't realize that good social skills are key in this field, especially when you need to give clients less-than-fabulous financial news.
