Hanoi Business Pulse
- Culture Formal, hierarchical, and relationship-driven. Government presence is strong.
- Lunch Break 12:00 PM - 1:30 PM.
- Pro Tip Best reached between 9:00 AM and 11:30 AM. Business in the capital is more formal and hierarchical than in the south. Relationships with authority and government are often important. Trust must be built through multiple polite interactions and formal introductions.
Istanbul Business Pulse
- Culture A bridge between East and West. Business is personal, and hospitality (tea/coffee) is a prerequisite.
- Lunch Break 12:30 PM - 1:30 PM.
- Pro Tip Aim for calls between 10:00 AM and 12:00 PM or 2:00 PM and 4:30 PM. Turkish business culture is highly relational; starting with "Nasılsınız?" (How are you?) and building rapport is essential. Avoid scheduling critical calls late on Friday afternoons.
