https://www.aviationinterviews.com/ has gouges at a cost if you're really worried about it. It'll be less than a half hour, they just want to get to know you and make sure you're not someone they wouldn't want to fly with.
Some example questions that I can remember:
What makes a good captain?
What's your greatest weakness?
What does CRM mean to you?
The interviewer also brought up a WWYD scenario involving an issue requiring a write up at an outstation on the go-home leg, with some pressure from the captain to not follow SOP. The answer is obvious.
