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.
Rio de Janeiro Business Pulse

- 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.
