Portland Business Pulse
- Culture Creative, informal, and values sustainability and technical excellence.
- Lunch Break 12:00 PM - 1:00 PM.
- Pro Tip The "sweet spot" is 10:00 AM to 4:00 PM. Expect a very casual professional environment (informal dress is the norm). Punctuality is still important, but the vibe is collaborative and egalitarian. Many in Portland value their work-life balance, so avoid late evening calls.
Shanghai Business Pulse
- Culture Highly competitive and fast-paced. Business is often conducted with a mix of modern efficiency and traditional "Guanxi" (relationships).
- Lunch Break 12:00 PM - 1:00 PM (Nap time is common).
- Pro Tip Respect the 12-1 PM lunch and rest window; lights are often dimmed in offices for naps. The best time to call is between 2:00 PM and 4:30 PM. Avoid calling during major public holidays like Golden Week or Lunar New Year, as business comes to a complete halt.
