@YoungKenyan:
Good to hear you too applied for the scheme! all the best to you!
As for your questions, a career as a pilot is indeed rewarding. However, it is a job that requires great commitment and more so, passion. I say this because of the levels of concentration needed during training, and during a flight too.
In terms of career progression, there is a path, as with most professions. the highest you can get to as a pilot would be the left hand seat i.e/ captain, which would depend on the number of hours you have logged and other factors..
Im hoping this answered your questions in brief..however, if you're unsure, i would suggest you read up as much as you can on the other careers that you might have in mind too, as im assuming from your post that you're a little bit unsure..all the best buddy
