The interview may something similar to an airline but I can assure you the work will be very different.
In the corporate flight department in which I worked we decided amongst ourselves that if the service we gave our corporate passengers was not equal to, or better than airline First Class, the company may as well close the flight department, save a fortune, and we'd all be out of work.
Like many in this sector of the industry we flew for fun and were paid for the waiting. At the interview I would suggest you come across as a team player who will do whatever it takes (within the law) to get the job done.
Good luck, it can be a rewarding and interesting career.
