totally rubbish that Engineer cannot command a good salary. I am in my 3rd year in Infineon as a software Engineer and i am having a comfortable 7k/month. If you are earning only 2 -3k+ then you should check yourself if you are lacking in skills tbh.
I have seen alot of untalented, bad engineers in my field of work and I am not surprised that Engineers on the whole are not well paid in SG. Even the first class honours graduates sometimes look like retarded when it comes to work.
