Mark Zuckerberg's Only Rule For Hiring

Arguably, Mark Zuckerberg is the founder of one of the most successful companies on the planet and it's a good idea to listen when he is offering a job advice.

Zuckerberg was speaking at the Mobile World Congress in Barcelona this week, where he revealed the main thing he looks for in a candidate while hiring.

"I will only hire someone to work directly for me if I would work for that person," Mr Zuckerberg told the audience. "It's a pretty good test and I think this rule has served me well."'

He added that the team looks for the people whose value align with the company's.

"Facebook is not a company for everyone in the world," he told the crowd.

"The most important thing is to keep your team as small as possible," he went on. "[Facebook] serves more than a billion people around the world but our team has fewer than 10,000 people. It's only possible because of modern technology. Big companies get bloated."

"When you're young you hear that you don't have experience to do things, that there are people that have more experience than you. I started Facebook when I was 19

"Don't discount yourself, no matter what you're doing," he added. "Everyone has a unique perspective that they can bring to the world."
