first of all ZTBL will provide only 16500, second thing u will be posted in your own area and third thing is you will be credit recovery officer and will remain OG-3 for at least 8 years. you cant move from ZTBL to any commercial bank or corporate.

on the other hand if u are satisfied with Bank al habib. this will be better.
if not satisfied, u should join ZTBL.
