    > X and Y are fundamental CS concepts

In 2024, the list of X and Y are fucking HUGE. I would like to see OP sweat in an interview on some "fundamental CS concepts" they have not used in the last 5-10 years. The lack of humility in some of these comment is simply stunning.

I worked with a guy who was absolutely a first class engineer. Very well paid; I guess about 300K USD. He had almost no experience in C++ for more than 20 years (mostly Java and C# for last 10 years). During a discussion, I mentioned that the original C++ std::map used a red-black tree. He was well-surprised that lookup was not O(1); instead: O(log2(n)). (My point: He knows about red-black trees, but was surprised the original C++ foundation library did not include a hash map with O(1) lookup!) Really: He would have failed an interview from this person based upon "fundamental CS concepts". Any software engineer, no matter how smart or experienced, has some weak spots in their fundamentals.

This is a strawman. Implementation details of a specific language library are not "fundamental CS concepts", unlike the specific topics I was talking about.

If you're hiring a C++ expert, then yes, not knowing the difference between map and unordered_map would likely be a disqualifying condition. We are not talking about C++ expert interview though.
