ball park figures would vary depending on where you go, hence my questions.
local companies pay the least - if you negotiate nicely you might get about SGD80 - 100K. local law firms - most do not take in lawyers with US experience unless they do a lot of US related work and require a US counsel (the bigger law firms have some US lawyers - but on the letterheads you would see "not admitted to practise in Singapore" or words to that effect). A local lawyer of 7-8 years' PQE should be a partner, and those in the bigger firms would earn upwards of 120K, excluding bonuses.
MNC's - I would imagine the pay scale to be higher than local companies. Foreign law firms - higher than local firms.
Check with legal recruitment firms, they would be the best to know.
