What should I ask when the interviewer asks if I have questions?

That moment catches a lot of people. They ask if you have questions, and your mind goes blank or you blurt out something you could have looked up. It is not a sign you are unprepared for the job. It is just an unrehearsed moment, and those are easy to fix. Think of it less as a test and more as your turn. You are allowed to be curious about the place that might take up your days. What does a good week look like here? What are they hoping this person will handle in the first few months? Questions like that show you are thinking about doing the work well. Write two or three questions on a card and bring it. Nobody minds if you glance at notes. It shows you cared enough to prepare, and it saves you from that frozen silence.
