Mate if you think to swap LUX. for Indonesia related with previous experience you had in Thailand, I honestly advise you to come and watch JKT first. It’s far different from your 1st Far East experience in Thailand. And be aware the Religion here is mainly Muslin, so a lot of traditions and costumes, as the praying times, the cordiality and subsequent respect for it, My driver stops to go Pray if we are on the road and I wait in the car Ex., although for me no worries I am used to it, and I speak a bit Arabic as well, so often I see myself teaching them the real deal.
English will be your main tool, but be alert to speak American English Slowly, I used to speak British English but forget it, slang it’s hard for them to understand, but they are brave and keen learners.
My Job, I am a Construction and Installation Engineer Manager for the National Oil Company, PERTAMINA, that’s why I am always on the move, meanwhile I have the chance to meet brilliant, Intelligent, and sometimes wicked people here, and I am very social as well and that helps a lot.
Job here there is a lot, but be aware you will need to pay upfront 1 year rent, Ex: for my Flat I pay 20,000 US, and that is a fully furnished place in the center of JKT, close to one of my offices.
Good Luck, and within my boundaries If I could help you any further, gives a shout mate.
BTW, almost all the Pilots from LION Air here are from Portugal same age as me more or less, very cool people but often to crazy and wild, almost all ex Air Force guys, you know what I am saying, I hope.
