I feel like I’ve heard this before, but in the early days of Google, Sergey Brin ended his job interviews in an unusual manner.
Finally, he leaned forward and fired his best shot, what he came to call “the hard question.”
“I’m going to give you five minutes,” he told me. “When I come back, I want you to explain to me something complicated that I don’t already know.” He then rolled out of the room toward the snack area. I looked at Cindy. “He’s very curious about everything,” she told me. “You can talk about a hobby, something technical, whatever you want. Just make sure it’s something you really understand well.”
I wonder if Mark Zuckerberg asks similar sorts of questions on his walks in the woods.
