Chicago Business Pulse
- Culture Practical, hardworking, and friendly. A major hub for logistics, finance, and manufacturing.
- Lunch Break 12:00 PM - 1:00 PM.
- Pro Tip Best times for calls are 9:00 AM to 11:30 AM. Chicagoans are known for being practical and direct but also friendlier than their East Coast counterparts. The Central Time Zone is the "Goldilocks zone" for North American business, allowing for easy syncs with both NYC and LA.
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.
