I am a foreigner currently working in Singapore. I had an engagement with Hays and was offered a role with one of the big MNC banks here in Singapore. The salary offered was nowhere close to what’s written in the salary report. I didn’t take the position and instead took an internal transfer. A good rule of thumb I think is to apply a 20 to 25 percent discount and you would be close to the real number.
