Rio de Janeiro Business Pulse
- Culture Relaxed but hardworking. Creative and media industries are prominent.
- Lunch Break 12:30 PM - 2:00 PM.
- Pro Tip Best call times are 10:30 AM to 12:00 PM and 2:30 PM to 4:30 PM. "Cariocas" (Rio locals) value an informal and friendly start to meetings. Always spend a few minutes on social pleasantries. Avoid scheduling anything for Friday afternoon as the city begins its weekend transition early.
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.
