I'm going to an interview to be a flight steward on Malaysian Airlines and i need help on the interviews..?

My interview is on the 28 of May... 7 more days to go, as you can see i want to be a flight steward, i need help on what to do and what NOT to do... What i need to wear and etc... I really need this job because i need the money for furthering my studies... By the way, i hope experienced flight stewards from Malaysian Airlines or some other Airlines with strict rules or those who did the interviews for flight stewards will answer this question.. I really really need this job..
