In our interview set, there is always a question that requires expert-level knowledge about a topic that the interviewee likely not know (well we'll ask them an easier question first and see if they can answer), then allow them to Google, and we watch the way they do it, their reading comprehension, analytical skills, generalization, assumption checking, .etc will all review. Harder to fake than leetcode questions.
Edit: our assumption is that someone can pull that off in 40-60 second Googling is a super-fast learner. So far we're doing great with our team.
