Tell me about a time you held a strong technical opinion and then changed your mind. What evidence moved you, and what did you take away from it?

Imagine you're absolutely sure the best route to a friend's house is the highway, but your GPS shows a huge traffic jam ahead. You might feel stubborn at first, but when you see the data, you switch to a side road. This question checks if you can let go of your ego when faced with new evidence, and learn from the experience.
