On the Call: Facebook CEO Mark Zuckerberg

Facebook Inc.'s second-quarter results blew past Wall Street's expectations as the world's largest social networking company continued to grow mobile advertising revenue. Facebook, which is based in Menlo Park, Calif., ended the quarter with nearly 5,300 employees up 33 percent from a year earlier. In a conference call with analysts, CEO Mark Zuckerberg, who earlier this year launched a political group aimed at immigration reform and expanding the number of visas available to highly skilled foreign workers, answered a question about hiring.

QUESTION: A couple quick questions. First on hiring, there's been a lot of discussion in the press about tech companies' need for more highly skilled workers, and I'm curious if you're feeling pressure to find that kind of highly skilled talent and what areas you find hardest to fill and maybe some successful ways that you're finding good engineering talent.

ANSWER: Hiring great people, especially engineers, is one of the biggest challenges that any technology company has. We're doing really well against the hiring goals that we have. But, I mean, there's a systemic issue where our country doesn't produce the volume of engineers that the companies would want to hire and I think that's a lot of what you hear these companies talking about. We're doing really well competitively right now, we have a really strong program on colleges where we continue to attract a lot of the best people who are graduating. We do really well at hiring senior engineers from across the Valley as well, but it's something we invest a huge amount of time and it's really important.
