Practically as a first jobber, how do you set aside money into which accounts so that you can make the most of the interest of banks?

I am using UOB One as it only need to fulfill 2 criterias, salary crediting and $500 spending for high yielding account.

A good way would be to allocate the your salary into 50/30/20. 50% expenses, 30% savings and 20% investment.
