This is kind of dumb because most of the examples just involve built-in language implementations or libraries that implement the stated algorithm.

For example if you use dict a lot in Python, that’s not at all the same as writing your own hash table with a custom chaining or probing algorithm for collision resolution.

The original quote from the whole homebrew saga is talking about needing to seriously implement these algorithms entirely yourself for a task. It was not talking about casually knowing a few fundamentals you loosely keep in your mind while using built in libraries.

Whiteboard hazing trivia interviews are also all about obscure implementation specifics, and they are not at all about knowing the coarse fundamentals. That was the entire point of criticizing Google’s parochial barrier to entry hazing crap.

While this author’s stated experience is cool, I think they entirely missed the point of what they are responding to.
