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.
Seattle Business Pulse
- Culture Tech-heavy, casual, and values innovation and nature.
- Lunch Break 12:00 PM - 1:00 PM.
- Pro Tip The "sweet spot" is 10:00 AM to 4:00 PM. Expect a casual professional environment (lots of tech-casual wear). Networking often happens over coffee; many locals are flexible with virtual meeting times but value their time in nature, so avoid late evening or weekend intrusions.
