The best interviews I've participated in (on either side of the table) have been when it's been more of a conversation, not an explicit evaluation. Yes, there's a power imbalance, and I'm not sure there's a way to fix that, but you can counteract it by treating interviews as a two-way street.

Interviewers don't need to be adversarial to determine if a candidate is going to be good for the role. Interviewees shouldn't be passive, and should be using the time to determine if the company is even a good fit for them.
