Good health care service, great and huge health club and swimming pool in the company, good free meal, free transportation for almost all places every day.

Hard workload. They do not trust and give freedom to software engineers. Managers do not manage engineers' workloads; they just assign and even change assignments every time because they are the superior boss.

For excessive security (sealing all mobile devices needed), engineers cannot carry any electronic devices every day. Engineers should get approval for "pensource" development for every commit and find it hard to access open information and material sites (Google Docs, SlideShare, or cloud service sites) because of security.

Managers should study software, development, and engineering. They are not a boss. They have no right to get a promotion by using engineers' bleeding. It will kill the company, even though the manager can succeed.
