Boston Business Pulse
- Culture Academic, professional, and values innovation in biotech and education.
- Lunch Break 12:00 PM - 1:00 PM.
- Pro Tip Best reached between 9:30 AM and 11:30 AM. Boston is a city of high intellectual standards; ensure your technical data is solid and your arguments are logically sound. The culture is professional and slightly more reserved than New York, with a high respect for expertise.
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.
