To be clear, I am not passing judgment on Oz - I think his accomplishments are impressive, all the more so given his day-to-day challenges. And I'm not at all a fan of the Leetcode interviewing culture either. My point was that Oz is not Carmack, Knuth, etc, so wouldn't fall into the exception bucket that Google cares about (unlike you or me). There are usually well-meaning reasons behind these processes, regardless how well they turn out.
