The sole founder of SpaceX, Elon Musk – and of course also know as the co-founder of PayPal and Tesla Motors – has a rather peculiar riddle he likes to ask when he is interviewing potentially new employees.

Here is the riddle Elon Musk asks:

“You’re standing on the surface of the Earth. You walk one mile south, one mile west, and one mile north. You end up exactly where you started. Where are you?”
