Ho Chi Minh City Business Pulse
- Culture Fast-paced, entrepreneurial, and very hardworking.
- Lunch Break 12:00 PM - 1:30 PM.
- Pro Tip The "Gold Window" for calls is 9:00 AM to 11:30 AM. Vietnamese business culture is energetic and relationship-driven; deals are often sealing during meals. Small gifts or gestures of respect are common in-person, but for virtual calls, maintain a warm, polite, and enthusiastic tone.
Sydney Business Pulse
- Culture Relatively relaxed but professional. Early starts are common to maximize daylight.
- Lunch Break 12:00 PM - 1:00 PM.
- Pro Tip Due to the significant time difference with Europe and the US, early mornings (8:30 AM - 10:00 AM) are often dedicated to international syncs. For domestic calls, late mornings are best. Be mindful that many Australians start and end their day earlier than their Northern Hemisphere counterparts.
