My supervisor suggested I use this method, and I think it's a pretty nice trick: when the interviewer asks if you have any questions, if there are any pressing things you wanted to share with them, turn it into a question for them.
For example, let's say you researched the school you're interviewing at and they didn't ask you anything about their school. When they ask if you have any questions, maybe ask something along the lines of, "Would you like to know why I decided to choose this school?"
I was a bit wary of using this method, but it proved quite useful in my interview, and I feel it demonstrated my genuine interest in my school.
Just a suggestion! Maybe this will help you 🙂
