Algorithmic ability has no correlation to the ability to write maintainable code, though. Most time at work is not spent demonstrating ability to regurgitate algorithms.

This is not true in my experience. I usually see a strong correlation between algorithmic ability and writing maintainable code. At various organizations I have worked for, I have seen that the ones with strong algorithm skills also happen to be critical thinkers who put a lot of emphasis on simple, elegant, and robust design and code.

So I am very surprised to know that this correlation I observe may not be true in general. How did you come to this conclusion?

I don't have data but my impression is that there is an inverse correlation. My guess as to why is that people with ability to manage a lot of algorithmic complexity don't seem to suffer when code is complex so they see no need to simplify things.

I'm afraid I can also only offer anecdata. Mine is based on hiring and then working with dozens of SW engs since 2008 (my first tech lead role), plus our student Incubator and open source projects (dozens of more junior devs).

The correlation between emphasis on simple, elegant design and code and algorithmic chops is indeed uncanny.

And I'd add "clarity of articulation" to that -- being able to express your thoughts and the problem/solution structure clearly and succinctly is a great indicator as well. Huge overlap with both code maintainability and algo quality.

I haven't seen this ever. Algorithmic skills have never been correlating with productivity or maintainable code in any of those 7 companies I worked in.

No causation, I'd believe any day. But correlation? I'd want to see a statistically rigorous test done before I'd believe that. Correlations are everywhere and pretty much all good traits are correlated with each other. Hell, even vocabulary size and reflex speed is correlated. And this is probably why even terrible methods for selection usually kind of work.
