Grace,
What is your nationality?
If you are Singaporean, you are basically out of luck. It will take you months to find a job that suits you. If you are desperate for a job, I suggest that you first obtain a citizenship from India, China, the Philippines or Malaysia. You then return to Singapore as a foreign talent. You will find yourself in great demand as hiring foreign talents is very much in vogue. Besides our esteemed Prime Minister and his gracious Father, LKY, are obsessed with bringing more immigrants to Singapore. Their target is 6.9 million inhabitants of whom Singaporeans may constitute only 30 to 40%.
Let me repeat: your chances improve greatly if you are a citizen of
The Philippines
Many recruiters based in Singapore are actively recruiting Pinoys/Pinays to work in Singapore. A major portion of UOB call center operations have been outsourced to the Philippines.
If you love fast food, you may wish to consider working for Jollibee in Singapore. You will feel at home working for the company as you will find many of your compatriots there.
India
If you aspire to be a top banker or consultant for shifting the funds of ultra-high net worth individuals to places like BVI, Cayman Islands and soon-to-be Qianhai district in Shenzhen, you'd better be an Indian citizen. Our Ministar for Finance is an Indian-Singaporean.
China
Ditto for [India]. Portcullis (Singapore), Barclays, HSBC, are currently grooming promising consultants to work in the tax-haven Qianhai district.
If you can't find a job after months of trying, you might wish to apply to further your study in Singapore. Please note that your chances of getting a bond-free scholarship greatly improve if you are a Chinese citizen. Don't worry. You just need a 6 on the IELTS score to qualify for tertiary education here. And graduating from college is easy in Singapore. Most of your compatriots have told me that graduating from Singaporean universities is just so easy.
