graduate trainee program basically is cheap general purpose kuli.
psychologically tie u as u feel needs to at least complete the program b4 leaving.
pays u entry level & tells u this is a gateway to learning.
they will throw u around different dept that temporary needs people, usually doing repetitive/tedious non important work cuz dept head also know u'll be thrown else where in few months.

there's another program that big corporates & bank usually hav, it's called "management Trainee".
basically this is for all the rich dato kids to "clock in" some "real world experience" to build their portfolio.

yes, that's what they tell u.
management trainee program ok, graduate trainee is a scam.
