Does it work though?
When I look at the messy Android code, Fuchsia's commercial failure, Dart being almost killed by politics, Go's marvellous design, WinUI/UWP catastrophical failure, how C++/CX got replaced with C++/WinRT, ongoing issues with macOS Tahoe,....
I am glad that apparently I am not good enough for such projects.
zero of those failures are of a technical nature.
The fact is that they fail is not evidence that leetcode interviews fails to select for high quality engineers.
