Hi
Hope somebody could help me.
I was been hired in an indonesian compny in jakarta and my working visa still on processing.
Since the job is urgent and the company planned to take me with a multiple entry visa.
Can somebody tell me with the ff questions
1. how many days validity of having a multiple visa entry?
2. While ongoing processing of my working visa do i need to have an OEC?upon entry?
3. What is the requirements in getting working visa?

There is no such thing as a working visa.
To work legally you must have:
A work permit (IMTA)
A valid immigration document (KITAS)
The latter is issued after you have the former, both applied and paid for by your employer.

Working without a work permit is illegal and leaves you at risk of fines, prison time, and deportation.
(any combination of the above but pretty much guaranteed deportation)
