if you want to make big buck with tnb, you can. but consider joining thier subsidiary TNB REMACO. Their function is more like a service provider in repair and maintenaince of power generation sector. They do utilize electrical and mechanical engineers a lot. Good exposure and learning process. Did my internship there. Many of their engineers are in hot demand by other big shots in power generation industry like Siemens, GE and other IPPs.

One more the thing, go to hell to the bumis / non-bumis issues. this kind of mentality will held back our nation to move forward. By the way, I'm a chinese. I  dont see any problem with that.
