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.
London Business Pulse
- Culture London business culture is generally formal but collaborative. "Flexi-Fridays" are common in the summer.
- Lunch Break Typically 1:00 PM - 2:00 PM.
- Pro Tip Avoid calling after 4:30 PM on Fridays as many offices wind down early for the weekend. Mid-week (Tuesday to Thursday) between 10 AM and 4 PM is the "Golden Window" for reaching decision-makers. Always start with a brief polite inquiry about their day before diving into business.
