Dweller is correct in what he says...
Nevertheless, ensure that you obtain school fee's for the school of your choice (you will need to getting cracking to find places ASAP if you take a job here), a housing allowance, car allowance and a possible relocation allowance...

The above is a basic guideline only. It really depends on which company and as dweller said, some companies have set grading systems that they do not move out of.
