Salary in big corporate

Helo,
i have been approached by some big international company with the opportunity to start work in Prague as Procurement Specialist.
I have 5 year of experience in this area.
I have no clue what kind of money i should ask for?
I would like to rent small studio for myself, travel back home to Poland once per month, maybe save a little bit?
Please help :)

Depends on the company you got the job for...
