nothing hard if you are fluent in spanish! they will ask you 12 questions exactly
you start with basic questions such as : what is your hobbies? what is your favorite sport?
then they will ask you to read 2 sentences ( to see if you have a good pronunciation )
finally they will ask you more specific questions related to the airline industry : you see a customer who didn't turn off in iphone and the plane is ready to take off .. what will you say ?
some exemples like that. good luck
