Yes. You do. And this is your time to ask the reasonable, thought-out questions you've prepared in advance. That means you've done your homework and read the job description and online reviews available and organized the most meaningful questions because you cannot ask them all. Usually, this question comes at the end of the interview, so listen carefully to everything they have told you because usually most of your questions will have been answered. This is not the time to ask random nonsensical questions that showcase your lack of preparation.
