Agreed that it's tricky, but there needs to be some feedback loop. Otherwise you end up with seriously broken processes that never get fixed. Companies tend to care about false positives more than false negatives, but there's a decent possibility that some companies have an extremely high false negative rate.

I think glass door provides the best feedback loop because it gives me an idea of what I'm getting into when I apply.

This is true, but perhaps you could do that passively by placing candidates in a re-sample queue and seeing where they work and for how long.
