I just got a job as cabin crew this past week, so I'm not sure if my insight is helpful!!!!! I had worked as ground-staff for another airline, and recently applied. They seemed happy that I knew a lot about the airline, and had customer services experience. I know for the airline I got the job with, onboard sales and sales-awareness was a key part of the interview, and I got asked a lot of ''what would you do if...''. Hope that helps!
