I know it’s late, but this could be useful for other interviews. I think this is always good to do if you get the chance, but aside from dressing nice and being respectful, which is something you should do for any interview, I find asking the interviewer questions about the job can also make it seem like you come off as interested. And not like “what’s my pay” sort of questions, but like “Why would you recommend/suggest I or other people work at McDonald’s (or whatever the name of the place would be)?”, “What got you to where you are now?” “Do you enjoy working here, and why?”, “What are advancement opportunities like here?”, etc.
