^I think it depends on the interviewer.
Mine was so chill. She literally said, at the beginning of our interview, that she didn't want our discussion to be artificially directed, and said we'll just discuss whatever we comes up naturally in conversation.
Never in the "interview" did she actually ask me any questions that felt unnatural or scripted. Instead, the entire two-hour meeting felt more like a philosophical discussion than an interview.
We talked about the election (the results had just been announced a day earlier), campaign finance and it's direct impact (does more money actually buy votes?) versus long-term implications (PACs can buy access, lobbying power), etc. But never did we actually discuss our personal political views. Sometimes I felt like we were debating, but it was always, always civil discourse.
She never had to say anything abrupt since the entire time, we were engaged in discussion and the questions came naturally. I also happened to talk about my extracurriculars, although I'm not sure if she would have asked me to elaborate only ECs had I not spoken about them.
Just relax! Everyone's interview experience will be different; I think I was very lucky to get such an engaging interviewer.
