Peru: First Name or Title?

From ExecutivePlanet.com

First Name or Title?

Considering that Peruvians tend to belong to a hierarchical culture (High power distance*) where authority is expected to be respected, people are addressed as Mr. (Señor) or Mrs. (Señora) and then the last name. Some professionals are called by a title. For instance, attorneys are called Drs. If one is dealing with a male Engineer, he is expected to be called Señor Ingeniero “lastname” (Mr. Engineer lastname) or just Ingeniero “lastname”. For either men or women in business and formal settings a shake of the hand is expected. In more informal settings, men shake hands, women kiss cheeks, men kiss women’s cheeks. Don’t use first names in formal settings until the other one invites you to call him or her by the first name.
