Well, i'm not trying to demotivate you guys on OnG companies especially Petronas. My dad worked in Petronas for 30 years. Yes, the benefit is good and i was insured with company medical care till i finish my uni. But nowadays is different from last time as mostly they require Bumi to enter (Sorry to Malays, i have no intention to highlight the racist remarks but this is the truth). For other races if you wish to enter, you must be good and real good in your academic and not just a bookworm. For Malays, it's far more easy to enter and simply can promoted to management level.
Previously under Hassan Merican management, he's damn good malay leader who treat everyone equal. That's why in his top management team got multiracial. He's emphasizing working performance instead of colour. It's pity that he left for Singapore.
Don't forget that other OnG company paycheck has to be equalise or below Petronas as there's one time, lots of malaysian were recruited by middle east OnG company with double or triple pay.
