Twizzlers, of course.
In November 2005, Zuckerberg told Harvard he was leaving. But before he left for good, Zuckerberg approached some of his computer science professors and asked them to recommend students who might be a good fit to work at Facebook. The Harvard Crimson caught wind of the story and reported on some of the interviews.
The media has since picked up on tidbits from the story, including Zuckerberg's controversial, now disavowed preference that all Facebook developers should be in college or just out. "The job lends itself to people with raw intelligence rather than industry experience," Zuckerberg said. "And if you're coming out of college, you have a really good idea of what Facebook is."
But we all missed the sweetest part, casually thrown in at the end of the Crimson's story.
"Hey Priscilla, do you want a job at the facebook?" Zuckerberg asked a passing friend. "I'd love a job at facebook," Priscilla Chan '07 responded, offering him a Twizzler.
