2500 K is low for an expat. its the minimum to get an employment pass.
I would shoot for a higher figure. Make sure they pay for you’re flights & somewhere to stay while you look for a place to live. Make sure its in writing or they may try to pull a fast one.
People work very long hours here. Expect to work 12 - 14 hour days from 5 - 7 days a week depending on the company. No leisure time here.
Design is not valued here like in the west. Just compare Creative
( singapore company ) to Apple ( US company ). This is the difference.
The country is very strict & laws for everything from flushing the toilet to chewing gum. It is the safest country in the world I think. Anything unusal is perceived as a risk. But good design comes from taking big risks.
So if you want good design go to Europe or US where anything goes.
You will not make $$ or good design in Singapore but you will experience a very unique place that could open doors to you later in you’re career as China is becoming more important in the big picture.
