I’d just take a look at the Questions on LC tagged as Google questions. That’ll give you an idea of what to study. That said, google is known for blacklisting from their interview database any questions found on the internet. What they do end up asking are twisted variants of stuff you find on LC, so doing that will provide a solid foundation.
