Sao Paulo Business Pulse
- Culture Warm and relationship-oriented. Personal touch and face-to-face (or video) meetings are preferred over emails.
- Lunch Break 12:30 PM - 2:00 PM.
- Pro Tip Mornings can start slowly; the most productive time for calls is between 2:30 PM and 5:00 PM. Avoid scheduling anything critical for Friday afternoon, as many locals begin their weekend travel early. Brazilians value personal warmth; always include a friendly greeting.
Tehran Business Pulse
- Culture Relationship-heavy and formal. Respect for hierarchy is paramount.
- Lunch Break 1:00 PM - 2:00 PM.
- Pro Tip The work week is Saturday to Wednesday. Thursday is often a half-day. Call between 9:00 AM and 12:00 PM. Iranian business culture is very formal and involves "Taarof" (a complex system of etiquette); be patient, polite, and avoid rushing into business without proper greetings.
