The vast, vast majority of employees working for American companies, even in an international deployment, don't tend to learn more than a few dozen catch phrases (Hello, Good Bye, How are you doing, where is the toilet, take me to the airport, etc...) for the country they are deployed to - they just hope everyone will speak english to them.
I'm wondering if Mark is the first Fortune 500 CEO to ever learn a different language while working as a CEO? I'm almost certain he's the first American CEO of a fortune 500 to learn mandarin while working as a CEO.
