Kolkata Business Pulse
- Culture Intellectual and heritage-focused. Business often involves longer discussions and consensus.
- Lunch Break 1:30 PM - 2:30 PM.
- Pro Tip Best reached between 11:30 AM and 4:00 PM. Avoid the 1:30 PM - 2:30 PM lunch window. Business culture is intellectual and values detailed discussion; avoid overly aggressive "hard-sell" tactics. Note that the city slows down significantly during major festivals like Durga Puja.
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.
