Tell me about a time you worked with someone you found difficult. What made it hard, and what did you do to make the collaboration work?

Imagine you're building a Lego castle with a friend who wants to use only red bricks while you think blue looks better. You can't just grab bricks from each other—you have to talk, compromise, and maybe build a red-and-blue tower together. This question checks if you can handle disagreements at work without breaking things or giving up.
