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.
Washington D.C. Business Pulse
- Culture Highly formal, networking-heavy, and influenced by government and policy.
- Lunch Break 12:30 PM - 1:30 PM.
- Pro Tip Ideal call window is 10:00 AM to 11:30 AM and 2:00 PM to 4:00 PM. Punctuality is non-negotiable. DC is a "Power City"; be prepared for very formal protocols and the use of professional or political titles. Networking is a 24/7 activity here, but business calls should stay within 9-6.
