The following are some good tactics to find jobs in Singapore (irrespective of your experience)
1. Create your profile on LinkedIn and start connecting to recruiters working in Singapore. They would love to connect back (trust me). I have 100+ recruiters connected to me.
2. Send a message to all the recruiters (whom you have connected) using LinkedIn Message (its free to send to send a message to a connection on linkedin)
3. Upload your resume on job portals as mentioned below which gives you all sorts of jobs, but beware you could get lot of duplicate jobs (which will leave your frustrating because there will be no response
STJobs.sg : http://www.stjobs.sg/
Monster.com.sg : http://monster.com.sg/
4. You may visit some special sites that are focused on specific niche like
(you get all jobs in start-ups, but due to prevailing laws in singapore, the chances of getting hired are less)
(you get all IT Jobs, yes only and only IT)
(you need to be earning $100,000 per annum to join this portal)
There are huge opportunities in Singapore, but its just the approach you take will matter the most.
