Hi everyone.
To all the aspiring pilots,
first and foremost, ask yourself
WHY you want to be a pilot. (Part of the essay anyway)
If you have difficulty convincing yourself with genuine reasons (
NOT money, traveling opportunities, interaction with people from all around the world) or actions which you had done to show why you want to be a pilot, chances are that you would have a hard time convincing the panel of interviewers as well.
After this you can move on to the technical, geographical, business aspect of SIA or the industry. (Which if you have an interest in aviation, you would have roughly known already.) I dont think its possible to really know everything but you should be able to judge for yourself.
Good luck guys!
