I got a job in SG thru networking. Sometimes good to maintain a healthy relationship with colleagues / vendors / clients. You never know what they can bring to you

You can try your luck around here https://www.mycareersfuture.gov.sg/, not 100% guaranteed to get a chance

FYI this website can only be logged in if you are local / work pass holder.

This portal is a government's initiative, if employers need to hire work pass holder, they will also need to post their job ads here and wait for ads maturity before they can tag the job ads with the work pass application.

For you, although you cant login, you can browse and see which companies are hiring. Then try explore the company's website or linkedin to get attention from recruiters.
