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.
New York City Business Pulse
- Culture Fast-paced and direct. Punctuality is highly valued, and meetings often get straight to business.
- Lunch Break Often "on-the-go" between 12:30 PM and 1:30 PM.
- Pro Tip Mornings (9:30 AM - 11:30 AM) are best for high-energy discussions. After 4:00 PM EST, most professionals are wrapping up or in "commute mode," making it a poor time for complex topics. Keep your pitch concise—New Yorkers value their time and appreciate directness over lengthy pleasantries.
