San Diego Business Pulse
- Culture Professional, casual, and focused on biotech and innovation.
- Lunch Break 12:30 PM - 1:30 PM.
- Pro Tip Best reached between 10:00 AM and 4:00 PM. Like much of the US West Coast, the culture is casual-professional. Biotech and defense are major industries; expect technical competence to be highly valued. Punctuality is respected, even in a more relaxed atmosphere.
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.
