Post Interview Questions

hi all, I was wondering, for those who conduct interviews for summer analysts, what are some the best questions that candidates have asked after the interview and during the “do you have any questions” phase? should the questions be firm/program related or just general advice and questions about the industry/process? I want to make a great impression and ask impactful questions that’ll help me get remembered. also, for candidates like me, what are some of your go to questions to ask? any insight from either side of the interview would be greatly appreciated!
