Hong Kong Business Pulse

Culture Fast-paced, efficient, and highly international. Values both Western efficiency and Eastern heritage.
Lunch Break 1:00 PM - 2:00 PM.
Pro Tip The best time for calls is 10:00 AM to 11:30 AM or 3:00 PM to 5:00 PM. Avoid the 1:00 PM - 2:00 PM lunch hour. Business is fast and professional; be prepared with your data and ready to make decisions. Like Singapore, punctuality and professional titles are highly respected.

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.
