More formal than you are expecting
Portuguese professional life runs on hierarchy, titles and long relationships. If you have worked in London, New York or São Paulo, the pace and the register will both feel off at first, and the instinct to speed things up is the wrong one.
Most of what goes wrong for foreigners is not the Portuguese. It is being too casual too early.
Titles, and who gets which
In most of the English-speaking world "Doctor" means a physician or someone with a PhD. In Portugal it means you finished university, and it is used.
| Title | Applicability | Social Requirement |
|---|---|---|
| Doutor / Doutora | Anyone with a University Degree (BA or higher) | Mandatory in initial/formal meetings |
| Engenheiro / Engenheira | Certified Engineers | High prestige; always used in address |
| Arquiteto / Arquiteta | Certified Architects | Specific to the profession |
| O Senhor / A Senhora | General polite address | Used when no specific degree is known |
Calling Doutor Silva "João" is not friendly, it is a mistake. The move to first names comes eventually, and it is offered by the older or more senior person. Wait to be invited.
Email is still correspondence
Portuguese business email kept the shape of a letter. There are formulas, and using them is expected rather than stiff.
