You have asked this and similar in several threads already which shows, to be blunt you have every chance of failing!
Simple solution: sit down with your note pad and think what the job involves, better still if you can take a flight and note down what you
experienced as a passenger. Clue: people and their actions both in the air and on the ground. You really must learn to think for yourself as asking here is not going to give you any pre-conveyed answers - they simply don't exist! Remember flight attendants sometimes have to think very quickly both at work and elsewhere.
