Those that has been there 20 years and above. Let me describe them. Too comfortable, afraid to move, know that they wont survive outside , afraid people outside is smarter, afraid of changes, even if company B were to offer them way higher, they wont go, not because of job security but afraid of competition. Because all the smart ones would have left. the lousy one stay, that is their competition. Very old mentality and will never adapt new ways of doing things.

Typing this, because i was one of them, came in e5 became e6 within 2 years, m1 within 3 years, m2 within 3 years. I took the plunge and left after making a decision not to work under an army personnel. I struggled at first, but pull up my socks. Now i might be an Zhuo bo m3 or a staff engineer in a manufacturing sector. i choosed the latter. in my 40s but did not regret my decision.
