Finding IT Jobs in CH

Hi,
i'm new to this forum it's been 1 month already since i started sending my cv to all internet and local working agency in Geneve but after all this time i didn't get even 1 interview (if it would be in italy at this time, i manage to had atleast 1 interview!).

What can i do for finding jobs in Swiss? any particular methods? maybe a spontaneus application to the company it's better in swiss? I'm using european CV is it good? thanks for any help.
