This is just a fun post but I noticed a poster on another site made a remark about how multinational teams are at Microsoft so I decided to see what countries are represented on our team.  The following are the ones I know on the UCAS team.

Brazil

Canada

Chile

China

Egypt

England

Estonia

France

Germany

India

Italy

Malaysia

Netherlands

Russia

Scotland

Serbia

South Korea

Trinidad & Tobago

Turkey

United States

These are just the ones I know - there are probably a few more.
