the new stuff includes what I want to learn too. I believe I can get in touch with both back end and front end including system side technologies in A Company. As long as I want to learn, I have the chance to touch with it. The thing is my job title and in charged part (which might occupy my working time over 75% ) are not what I like and not what I want to sharp my skill for...

B Company, after dealed with them couple of times, look like the IT Director and the other fellow knowing little about the professional skill. it's a combination of legacy and new development, but fully focus on my professional skill. I can tell they rely on me a lot. otherwise, they won't agree to give me the suppervisior level's salary. I might need rely on myself to solve all sort of issues...

Thank you 老土!
