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.
London Business Pulse
- Culture London business culture is generally formal but collaborative. "Flexi-Fridays" are common in the summer.
- Lunch Break Typically 1:00 PM - 2:00 PM.
- Pro Tip Avoid calling after 4:30 PM on Fridays as many offices wind down early for the weekend. Mid-week (Tuesday to Thursday) between 10 AM and 4 PM is the "Golden Window" for reaching decision-makers. Always start with a brief polite inquiry about their day before diving into business.
