Invert a binary tree.
I think you just explained extremely clearly, why hiring managers aren't really into that sort of candidate.
Well, now that you mention it... no.
But that's just fine. "Meaning" doesn't have to be some big ol' thing. So the whole universe is meaningless; so what? Big whoop.
And in this big, empty universe, maybe all that matters is finding something beautiful, something rare, something brilliant and destined for greatness, something like... a candidate who can code a few lines worth of decent code on the spot.
The truth is, if you give the candidate a moderately realistic problem and a blank canvas, the first 5 minutes of watching their hands on a keyboard (or equivalent, if they don't have hands) will probably tell you 80% of what you need to know. If you know what to look for.
is there anything that isn’t meaningless, then?
their idea of knowing X, Y and Z likely differs from yours, as well. what will you believe or trust from a resume?
(personally i don’t trust any specific element and just look for an overall tone, and then ask about the specific interesting bits.)
