By talking with my classmates in the language school, I really got very attonish when my colleagues talked to me about their salaries: a Spanish architect with international experience got an offer of CHF 3'500.00 brutto! Since me, as reception manager, my HR manager controll very good that I pay a person without experience, just because she/he has a aprenticeship certificate CHF 4'100.00.
So sd help for others:
Here is a goverment official calculator of salaries (just available in German, French and Italian):
