well, the chances of getting a permanent contract are somewhere near zero. Its the maxis policy now. Once the two years are up, they *might* renew the contract, but it will be for another 2 years, or 6 months, depending how long they need you or how long before they can replace you with a new person who will accept a lower salary.

contract wise, your salary will be generally higher in exchange for less benefits and longer working hours. It would be a good experience if you're a fresh grad looking to get a foothold in the job market as maxis experience will look good on your resume.
