As one of the youngest and most successful entrepreneurs in the world, any career advice from Mark Zuckerberg should probably taken fairly serious, or at the very least written down.

Speaking at the Mobile World Congress this week - the world's biggest wireless phone fair in Barcelona - the 30-year-old Facebook founder was asked the main thing he looks for in a potential employee.
And his answer was as simple as it was significant. "I will only hire someone to work directly for me if I would work for that person," Zuckerberg told the gathering at a town hall meeting. "It's a pretty good test."
Earlier this week, Zuckerberg was forced to fend off complaints that his hugely popular social network was getting a free ride out of telecom operators who host its service on smartphones. He was confronted with tensions between Internet giants such as Facebook and Google and telecom firms present at the Congress.

Executives have complained that some Internet services' smartphone applications generate revenue while it is the telephone companies that are forced to invest in the networks that host them.
Zuckerberg later defended himself in an appearance at the congress alongside the heads of several telecom companies with which he is working to launch smartphone Internet access in developing countries in Latin America, Africa and Asia.
"We have these services that people love and that are drivers of data usage and we want to work this out so that way it's a profitable model for our partners," Zuckerberg said.
