I used to waste the 'any questions for us?' part of interviews. Treating it as a real round changed my results.

For the longest time I'd end interviews with a limp 'nope, I think you covered everything.' Then I realized that's often the part they remember.

Now I bring three or four real questions: what does the first 90 days look like, what's a project the team is proud of, how do you handle disagreements on technical decisions, what would make this hire a success in a year. It turns the last five minutes into an actual conversation, and twice interviewers told me my questions were the best part.

Bonus: their answers tell you whether you even want to be there. It's not just them evaluating you.
