HK might be an ok place to work if you are top management or in a high paying sector like a finance/trader/doctor/lawyer type job.
Don't listen to Freely since anything about Mainland is bad and everything outside of it is great (HK, Macau, Taiwan). He never lets facts get in the way of his opinions.
Truth is (I have worked in HK and have friends still working there in different places), HK is a cut throat place. You will have to work long hours and tedious. It rivals American work pace. Euro is very relaxing in general in terms of working because they like to take time and enjoy life. In HK, if you stop and smell the roses, your job might be gone the next day.
My aunt in law works in a marketing firm and workers pretty long hours with lots of stress. I would say they are in the middle class range. Their family lives in a 80SqMeter condo on the 20th floor. As the flip side, my college friend works for a bank as a trader in HK and he works over 120 hours a week. While he gets paid handsomly, he still cannot afford to buy a place of his own (abait he has higher tastes). So the housing situation in HK is quite bad and expensive. In another words, if you want to work in HK, make sure your living situation is taken care of before anything else.
Food is excellent and cheap for the most part. It has a hint of authentic Cantonese cooking and many foreign styles of food as well.
Culture is very mixed. After 100 years of British rule, a lot of locals can speak words of English, so you should be fine if you only speak English. There are many immigrants (countryside as well as Chinese from other provinces) that live in HK.
One of the things I don't like are the people. They are very pretentious (of course not everyone, but definitely more than other cities in China) and fast paced. They think they are better than most Chinese because they live in HK and think they are higher classed. When in reality, they were all fishermen just a century ago that were ruled by a foreign country. Don't know why you would be so proud of that.
Overall, I would say it is a decent place to work. However, there are better options, especially in Beijing and Shanghai.
