It's often possible for you to drive the interview rather than waiting for the interviewer to ask your questions. Bring up and expound on your skills if they're not asking the right questions.
Whether or not I get an offer, I tend to the enjoy the process more when I try to be collaborative in an interview process, vs waiting to be asked questions. I naturally want to show off some stuff and ask questions - if even that doesn't go well, it's probably not going to be a good culture fit, regardless of whether I can do the raw work.
