San Diego Business Pulse
- Culture Professional, casual, and focused on biotech and innovation.
- Lunch Break 12:30 PM - 1:30 PM.
- Pro Tip Best reached between 10:00 AM and 4:00 PM. Like much of the US West Coast, the culture is casual-professional. Biotech and defense are major industries; expect technical competence to be highly valued. Punctuality is respected, even in a more relaxed atmosphere.
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.
