I heard that it will be easier to get a job in Singapore when you already have a DP, compared to when you have no residential status at all.
But I find it's really hard to get a job here, even after I received my DP.
Speaking about my background, I was working as an engineer in an oil & gas company in Australia for 3 years. To be exact, my job is a field engineer, a kind of mixture between Petroleum-Mechanical-Electrical Engineer. We work in an oilfield, in a rig (Deepwater Horizon anyone?

The company is renowned for those who work in the energy sector, as it's the largest oilfield service company in the world.
I graduated from a university in Indonesia, not Singapore.
I've tried applying around 200-250 vacancies, in various areas, ranging from oil & gas to non-oil&gas related vacancies.
From engineer to consultant. From manufacturing industry to consumer research company.
Man, I'm no longer picky about applying jobs.
They always rejected my application.
Even after my wife's friend who works as a senior HR staff in a multi-national company asked for my CV in order to help me getting a job, I still haven't landed any job...

I even applied to some jobs as a call center guy & sales over the phone.
They did invite me for an interview.. but I'm still trying to find a job where I can develop my career. Not saying that a job as a call center guy is bad though.
I understand that oil & gas or energy sector is a big no-no right now as the oil price is still lying low.
I don't see too much oil & gas related vacancies anyway, therefore I applied to a lot of vacancies with little relation to my experience.
Is there any other foreigner who experience the same issue?
Or is it really hard to get a job as a foreigner in Singapore nowadays?
Or probably it's hard because of my background in the oil & gas sector and companies in Singapore is really picky?
I'm trying to get some suggestions based on people's experience getting a job in Singapore.
Sorry for the long post, Thanks a lot!
