Seoul Business Pulse
- Culture Extremely hardworking and hierarchical. "Pali-pali" (hurry-hurry) culture drives rapid growth.
- Lunch Break 12:00 PM - 1:00 PM.
- Pro Tip The ideal window is 9:30 AM to 11:30 AM. South Koreans value speed ("Pali-pali") and expect rapid responses. Avoid the 12-1 PM lunch hour strictly. Ensure you follow hierarchical protocols if senior leaders are present, and never arrive (digitally or in-person) late for a call.
St Louis Business Pulse
- Culture Midwestern values of friendliness and hard work. Business is professional but often involves personal connection.
- Lunch Break Typically 12:00 PM - 1:00 PM.
- Pro Tip Operating in Central Time (CST/CDT), St Louis is a perfect bridge for coast-to-coast US calls. Reach out between 9:00 AM and 11:00 AM for the most engaged responses. A friendly, personal opening is culturally expected before diving into technical or business details.
