Rio de Janeiro Business Pulse
- Culture Relaxed but hardworking. Creative and media industries are prominent.
- Lunch Break 12:30 PM - 2:00 PM.
- Pro Tip Best call times are 10:30 AM to 12:00 PM and 2:30 PM to 4:30 PM. "Cariocas" (Rio locals) value an informal and friendly start to meetings. Always spend a few minutes on social pleasantries. Avoid scheduling anything for Friday afternoon as the city begins its weekend transition early.
San Francisco Business Pulse
- Culture Innovation-focused and casual. Values disruption, speed, and technical excellence.
- Lunch Break 12:30 PM - 1:30 PM.
- Pro Tip Best reached between 10:00 AM and 4:00 PM. Expect a casual, tech-first vibe—informal language and dress are the norm. However, technical competence and speed are non-negotiable. Many in the Bay Area work non-traditional hours, but standard business times remain the safest bet.
