Elon Musk's interview question : Where are you ?
Solution
One of Elon Musk’s favorite interview riddles is deceptively simple: “You walk one mile south, one mile west, one mile north — and end up exactly where you started.”
While many guess the North Pole as the answer, there is a deeper mathematical insight that reveals **additional locations** satisfying this condition.
In this explanation, we will explore both the obvious and the less intuitive solutions, using geometry and logic.
This classic riddle from Elon Musk’s interviews highlights how geometry and the curvature of the Earth allow for **multiple valid solutions** beyond the North Pole — namely points near the South Pole.
It’s a beautiful example of how simple directions mask complex mathematics, and how thinking beyond the obvious reveals elegant, counterintuitive results.
