Be ready to go back home with empty hands unless you are local, obviously as it happened with the Airasia roadshow on june 10th they will let you come here, because is more fun in Philippines with plenty of promises, and then face the reality, NO EXPATS right now, they will keep you file for further recruitment and then you can enjoy some days off in Manila thanks to them.
Do not put too much expectations on any Philippine carrier, they are master of keeping you on stand by for ages, take it as a holiday trip, meet some locals girls and have fun, the positions are already taken before the roadshow, but bringing expats here its always a benefit for the country.
Contact management, send your resume and wait, they even make skype interviews, no need to waist a flight ticket to come.
