Houston Business Pulse
- Culture Focused on energy, medical, and aerospace. Professional and direct.
- Lunch Break 12:00 PM - 1:00 PM.
- Pro Tip Reach out between 9:00 AM and 11:30 AM. Houston is a practical, results-oriented city. The Central Time Zone is ideal for North American coordination. While professional, the culture has a touch of "Southern hospitality," so a friendly opening is always appropriate.
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.
