- Lunch Break 12:30 PM - 1:30 PM.
- Pro Tip Reach out between 9:00 AM and 11:30 AM. Professionals in Rotterdam are famously direct and value efficiency above all. Avoid overly complex pitches; focus on practical solutions and clear results. Respect the standard 9-5 workday strictly. Direct honesty is highly respected.
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.
