Leetcode. They love their leetcode questions.
Be prepared to answer a lot of non-technical questions. We reject technically competent people if we don't think they're a good culture fit.
Here are some resources for non technical questions i saw on GitHub - https://github.com/yangshun/tech-interview-handbook/blob/master/non-technical/behavioral.md#airbnb
