Well considering I made the initial statement, no, it's not. A company I used to work for once hired exclusively from the must-have-Python-experience pool (not my decision) and the cto fawned over how well he solved this "well-known-leetcode problem", and he utterly failed my problem, which tests for actually useful competency... of course he was hired -- and turned out to be a complete lemon. I remember that hiring round distinctly, everyone we interviewed for that position (n~10) was competent for the leetcode problem but never did basic things in my interview like "write tests", "don't try to make a complicated algorithm", etc,
even when told explicitly to do/ not to do those things.
Outside of that I interviewed several of my friends (I know them from a non-programming context, so I don't know their competency) who were predominantly python devs, and completely noped out of them for the same reasons (and these were my friends).
