Be yourself, be sincere and enjoy the other guys from around the world you will be interviewing with. They all will have their reasons for coming to EK, but most will be coming from companies that are losing money, not growing, or on their last legs;they are looking for stability in their lives and a profession with a future.
The interviewers just want to see that you can get along with other people, communicate effectively, and oh yes, fly the jet. Good luck! Cheers!
P.S.- If you're not stabilized at 1000ft.....GO AROUND!!
