Hi,
You must know that life in French polynesia is really expensive (food, taxi, housing)
Regarding the job, it depends in what field you work. But you must know that in Tahiti, if you want to have good perks, good job position, it's (really easier) when you have contacts, because it is the way it works out there, due to the restrained number of people.
Corruption is also a very important part of the culture.
If you have any other question, don't hesitate
