The salary depends on your grade. For grade 35 (executive officer) minimum salary starts at RM2,900 with minimum increment of RM330 each year. Executive officer's salary is capped at RM8,500, if reach the amount the only increment you can get is if you get promoted. Meanwhile grade 36 (asst. manager) minimum starts at RM3,400 with minimum increment of RM380 annually. Asst. manager's salary is capped at RM11,500. But I have no idea about the salary for grade above 36.
CIMB gives 25 days AL, 30 + 60 days sick leave, 7d study leave, 10d marriage leave and full medical coverage in panel clinics/hospitals. I might be wrong but I think they don't fully cover medical expenses for officers holding manager positions and above.

Yup that’s the minimum. If your performance is good you’ll get higher increment. If your work is shitty, you will still get minimum increment. But you will not receive bonus. And your boss will treat you badly until you resign yourself.
