Denver Business Pulse
- Culture Professional, active, and values a strong work-life balance.
- Lunch Break 12:00 PM - 1:00 PM.
- Pro Tip Ideal call window is 9:00 AM to 11:30 AM. Denver is a hub for aerospace, tech, and energy. The vibe is professional but influenced by the outdoor lifestyle. Mountain Time is great for coordinating with both US coasts. A friendly, collaborative opening is always appreciated.
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.
