It is very hard to time that a320 type rating thing.
In Asia, the two companies that have been hiring (non-nationals) without time on type has been Cebu and Macau. However, both of these get applications en masse from people with thousands of hours and an a320 type rating.
My advice would be to not do a type rating, unless you have talked directly with an airline, they have told you what type rating center they use for their pilots, and that they would definitely interview you afterwards. That's the smallest guarantee I would go for...
However, for one in your position, it's not easy in any way shape or form to go directly to a jet job.
The other option, is to be lucky enough to time it exactly when with one of these companies hire, because, after 6 months, some companies won't touch you anymore unless you go do a recurrency again..
Just having an a320 type rating from a random provider, with no job prospects, no programs, or anything else, is gonna be a 90% chance of being a complete waste of money.
