if the only person for the position is you and you exceed the company expectations during the interview you might get the proposal (formal offer) the same day or within a few days (a week).

Now if there are others to be interviewed for the same position then a final selection is to be held and those who reach the "short list" will be notified and then the proposal sent for review, agreement and signature to start the employment process. These steps could take longer (1 month up to 5 months) depending on the process itself.

Also bear in mind that during mid Aug to mid Sep is the celebration of the Holly month of Ramadan and that certainly will slow things pretty much.

Anyway if you need further assistance just drop me a PM. I'm also a venezuelan working here.

Regards!!
