I am going to have to let you find that out for yourself. My only dealing with Hess was over my ARC when I was looking for a job. They told me I could not use my family-based ARC and had to get one through them. Maybe it was a mistranslation, but that is what I was told. Anyway...
I am sure it is different from teacher to teacher, depending on perspective, but...
My first two jobs here, I was replacing a teacher who had had enough and wanted to go home. One from the US, the other from SA. It was their first jobs, and their first time away from home, and I will admit that Asia is probably not the best place to go for first-timers. They didn't like the food or weather. One left in the middle of the night. Just...gone. The other made an effort to stick around through the transition.
If you are teaching in Taipei, or Xinbei, you might have an easier time. The further south you go, the less and less foreigners for you to talk with and share experiences with directly.
Some kids will take to you, others will not. One key to remember is to follow through with every promise or threat. If you promise pizza for doing good on an exam, you better deliver. If you threaten a deduction in points, or to take away a prize or whatever, you better do so. Otherwise, they will learn how to manipulate you.
Play games with your kids, but keep it simple and always change what games you play. The kids hate repetitions.
As you get into it, you will learn what to expect. Keep in mind that here is a results orientated system. That is, they want high test scores. They being parents and bosses. If you can deliver that consistently, then you will be fine with both.
The English learning of 80% of your students will begin and end when they arrive and when they leave your school. Rarely will they do [your assigned] homework, or anything on their own. They practice in your class almost exclusively. This is bad for language learning since it requires X amount of input. The concept of "you get out only what you put in" appears to be completely lost on people over here. (and from what I understand, this is creeping in to the West as well).
You have a support base here. Any questions or concerns, you can ask here. To paraphrase Flakman from above, give it time. But, not too much time.
