You will be accustomed to dealing with passengers as well as what is required to be involved in working for an airline.
If you do want to work for Saudi Airlines then you will of course have to face a number of interviews. The interview process is essential because as far as the employer is concerned they are looking for experienced people who know what it takes to work for such a prestigious airline. You have to take into account that if you are male and you want to work for this airline then it is essential that you are a Saudi national.
What also might be just as important in order to work for this airline is whether or not you are able to speak other languages. This is because you will be dealing with a number of flights and international travellers who are not just people from Saudi Arabia. But if you do speak Arabic this is very important and will dramatically increase your chances of getting an interview and succeeding in working for this airline due to the fact that you will be face to face with a lot of nationals who can only speak Arabic. This also applies to other airlines that you might want to work for.
This is exactly the same situation when applying to Lufthansa or Air France because if you are able to speak German or French respectively then this is a huge advantage.
