1. never work in the accounting filed unless you are employed by Big 4 (believe it or not, the accounting field is full of discriminations. If you are not from Big 4, you will find it extremely hard to progress with your career).
2. never work in the back office for financial industry e.g. operation, compliance, HR etc unless it is an i-bank (back offices in commercial banks are cost centers only. There are little chances for promotion. If you are not promoted, your salary increment will be very small, usually several hundred dollar each year).
3. if you wnat to work in a commercial bank, try the front line e.g. fpm, pfpm, cso etc.(having said that, you should bear in mind that the quota and traget are really high and hardly achievable).
Accounting is better because the demand from China is high.
Even though you do not want to work there, the demand may as a result recruit numbers of HK existing accountant, then the opening position in Hong Kong is correspondingly becoming more and more.
