I've always wondered if these companies have data to support their hiring routine or if it's just a filter to convert an overwhelming number of applicants into a pool that's manageable?

On the other hand, reversing a tree and problems like fizz buzz are pretty low bars...

Of course they have data, but there are an infinite number of possible interview strategies and the current approach is at best a local maximum.
