“Autorizzo il trattamento dei miei dati personali ai sensi del D.lgs. 196 del 30 giugno 2003.”
You write it as the final line at the end of your CV to authorize the recruiter to use your details.
If you are sending your CV by regular mail, you should initial each page of the CV and sign the final one. The signature usually goes along the long side of the paper.

A CV photo is not requested by Italian recruiters.

CVs should be brief (1 to 2 pages long) and to the point.

CVs are sector specific, but always include all your personal details: sex, place and date of birth.

In most cases hobbies are not mentioned. Likewise, information such as your career objectives, career goals, or personal traits and skills are usually not included in a CV for the Italian job market.
