Spoke to the HR person as to why the salary range is now 16k-30k compared to 25k-33k
It turns out that they changed the job spec (and adjusted the salary) at some stage. Problem is that they never told anyone about it.
They are apparently going to be having a meeting between IT and HR to see why this happened and what they may do about it (if anything).
Only thing that I can do is to wait until Monday and hear what the result is.
