Input: (CNN) -- Mark Zuckerberg went back to Harvard on Monday on a recruiting trip, his first visit since he dropped out of the prestigious university to found social-media giant Facebook. Clad in his trademark hoodie and T-shirt, Zuckerberg told reporters, "This is a great time to come." "There's a lot of really smart people here, and a lot of them are making decisions on where they are going to work when they graduate in the next couple of weeks," he said. The university posted a slickly edited video on YouTube of Zuckerberg's outdoor remarks. Zuckerberg quit Harvard and moved to California to found Facebook in 2004. The university's student newspaper, The Harvard Crimson, says he was back on campus for the first time since he left to recruit students for internships at Facebook.Mark Zuckerberg dropped out of Harvard University in 2004The Facebook CEO visited the campus on MondayHe returns to recruit engineering students for internshipsIt is his first official visit since 2004, The Harvard Crimson says
