Singapore and Asian companies are notorious for giving jobs to their own family members, clans people, same village etc. That is why the Ang Mos began playing this game. Back home they can't get away with it.
The Government however opened the flood gates thinking that they will get quality but it tuned out that these foreigners in many cases were under qualified or poor performers. Singapore clubs such as SRC, Singapore Swimming Club in the recreation front went thru various Ang Mos at CEO who failed miserably, brought their friends in with CVs that was not true. Even Cisco had a unit that was made of Australians who were drinking buddies and the management was truly hoodwinked.
In Australia, the respective trade or vocation rep must validate an migrants coming thru any of the occupational category to ensure that they must meet standards. We have none of that.
