Unfortunately, Glofish has pretty much summed it up with regards to experienced pilots applying to work out here.
However, if you're in you're early 20's with minimum experience of 2500 hours and no previous command - it's probably a viable option as you can see the world for 5 years then disappear. You would still have enough years left to settle into a longer-term airline back home where you can then enjoy a settled family lifestyle etc having already seen the world.
For those considering leaving stable airlines or commands and following the dream of a flying a shiny widebody across the globe it's a huge call... the time to command here will be looooong as most skippers here are both too young to retire and too financially/family-committed to leave (despite the talk on this board).
Good luck in whatever decision you make, just spend a lot of time mulling it all over and consider the consequences in the far future. It IS a one-way ticket for most.
PS: Really don't worry too much about the interview it just
looks like a big deal. All they are looking for is the ability to fly on one engine safely and have a decent enough personality to not provoke violence from the guy next to you on an 18-hour shift to LA or San ran... Everything else has very little weight in the process ( Compass tests etc )...
