How do I evaluate a company while they interview me?

You have grown past a fear that grips most people. You can walk into any interview and connect, and you know it runs both ways, that you are sizing them up as much as they are sizing you up. That is not arrogance. It is maturity, and it puts you in a far stronger position. Because you are not desperate to be chosen, you can pay attention to what matters: whether this is a place you would actually want to spend your days. The same steadiness that helps you connect also lets you notice things others miss, how they treat you, how they answer hard questions, whether what they say fits what you see. So use the room fully. Prepare a few real questions about how they work, how they handle conflict, what happened to the last person in the role, and watch how they respond, not just what they claim. You are choosing a chapter of your life, not just seeking approval. Interview them like it matters, because it does.
