Philadelphia Business Pulse
- Culture Hardworking, direct, and values heritage and education.
- Lunch Break 12:00 PM - 1:00 PM.
- Pro Tip Reach out between 9:00 AM and 11:30 AM. Philadelphians are known for being direct and hardworking. The city is a major hub for healthcare, biotech, and research; technical expertise and clear, data-backed arguments are highly valued in professional discussions.
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.
