And then you face candidates with a few years on their resume who cannot perform a dfs when explicitly told to! (This is where some of my screenings end up after a few rounds of simplifications/hints for the initial problem)

I have a hypothesys that there is a huge layer of companies who do not "hire the best" because this is not crucial for them and I just do not have experience of what is going on in there, having only exposure to the people who did pass this filter in the software-first companies I have worked at (and I have always enjoyed working with people I have landed with in every company). I do not feel strong enough to do a deeper research on this hypothesis though.
