Unless UOB's MA is known to be neogtiable, or that your friends have prior working exp or a relevant Masters, the joke's on you.

Otherwise if you were indeed successful in your nego for a higher salary, then I hope the entire batch of MAs going in finds out and ask for their equal share.

Maybe you should have just made it into a foreign bank instead so that you don't have to nego in the first place yeah? Even SC or Barclays pays better than 4K. 🙃
