See If You Can Solve Elon Musk's Favorite Brain Teaser (to Ask Prospective Employees)

There are probably plenty of people out there who are interested in working for Elon Musk. He's rich, his companies are successful and he's also involved in extremely cool and interesting industries. But if you want to work for Musk, you're going to need to answer one question first.

A few years ago Musk revealed the question he asked all prospective employees when he was hiring people for SpaceX. Many tech companies will ask bizarre riddles or brain teasers to employees to test them. It's not necessarily about whether or not the person gets the question right as much as it is seeing what they answer and why, and to get an insight into how their brain works.

So what was Elon's question? Here you go:

"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?"

CNBC asked this question to random people on the street in New York City. The most popular answer was "Earth," because if you were standing on the surface of the Earth and walked any direction, you'd still be on the surface of the Earth. And while that is a good answer and technically true, it's not the correct answer.

Want to know the correct answer? Here it is:

The North Pole. If you followed the directions at the North Pole, you'd make a triangle and end up back at the North Pole.

There's a second possible answer as well that's more complicated. It has something to do with being in a one mile radius of the South Pole, but it just makes more sense to say the North Pole.

I wonder if tech companies are finding it harder to get good workers because now prospective employees spend the night before their interview researching ridiculous riddles in order to get a job.
