Hi, friend. I know your feeling on long-term looking for a job. I spent more 5 months applying for a job. Fortunately, I got a job at last, which I ever didn't want to interview. So, remenber
1)modify your CV, especialy your experience or practice;
2)you can try via JobsDB/Jobstreet/ the revelant agent;
3) You must read The Straits Times, especially Saturday;
4) You need to keep your good feeling everyday;
5) try again and again.

Haha, Good luck to you.
