Hi, usually for interviews, you would have done some research on the company and the position before going for it, so what I usually do is that I would have a list of questions to ask (usually about working culture, how big is the team, who you will be working with, etc), and will just remember them and ask them when the interviewer(s) asked if I have any questions for them, so I guess the idea is to go for the interview fully prepared, and try not to take out the paper with the list of questions, as I think it seems rather unprofessional.
