after December is a good time already, cause many people will cabut after getting AWS.
get a local number and add it to your resume..
some employer will hesitate to call foreign number as the candidate may not readily be available for interview.

Well, many also told me that I am fresh graduate. With less than a year working experience, it is unlikely for me to get a job.
I have proven otherwise, manage to get a job here. Just dont disheartened if you never get reply as soon as u expected.

there's a lot, i land my job from LinkedIn.. there's also JobsDB, STJobs, try google it though 

Well, when I tell my senior when I am start working in my Malaysia firm.  He telling me how great to be in here my Malaysia company, there are a lots of things to learn. And along the three months, nothing much I have learnt which can make me very excited abt the job. Telling me how his friends sucks over in Sg doing something boring.
Now, my first week in Sg, my team is totally new, I get to do a lots of things that I was not allowed in my previous firm despite I am a freshman.

If you feel the company does not let you learn, try few months, and you can quit and try to search for new one. Or just wait for two years, get PR, and search job from there.

You don't have a valid permit to work in SG, I don't think the employers will take such risk?

Nope its not possible
You can only stay 30 days at a time under a visitor visa

U dun wait in singapore for interview

U find job and wait for interview back in malaysia

Oni come here when u got a confirmed date

Just by staying in singapore wun help u much on finding new job

To add on, most of the time will do phone interview first.

Not weird as long as they can reach you.

I did the same when my sis wanted to comeover.

Company call me, I told em "she just went out for lunch or whatever and left her phone, leave your phone and she'll call back." bla bla.

Even if you could, do you know how much RM i will cost you to stay in SG for 6 months without a job? 
Plus after doing all the online applications its just waiting at home for them to call you, hardly worth you moving there for 6 months

As the others mentioned above, just apply from MY and travel down if you have a face to face interview

Ask them if can provide Skype interview. My HR did this for most foreigners

Maybe u can try to send the job applications on the internet before u come over. Im from IT and also a freshie. Got my offer letter only 10 days when i come here. Be confident, 6 months is just too long lol probably max 2 months u can get a job here already depends on your qualifications.

i'm from UTAR...
