It depends on who you're talking to and what you ask. An IC interviewer's hands might be tied for some questions for legal or other reasons no matter how confident you are. Some questions are okay though, for example if you ask about a system design question they asked you, and they tell you their question was based on an actual business problem they have and your answer described how they've actually solved it. Obviously that's a good sign. Also, if you're talking to the hiring manager, particularly about salary and start dates, you might as well just ask if you're going to get an offer.
