Algorithms was one of 18 courses in my CS major.

You want to check my computer science background, ask me about: regular languages, LR0 grammars, interpreters, compilers, system calls, threads, virtual memory, concurrency control, TCP, consensus protocols, raytracing, scene segmentation, sensor fusion, database indexes, block cipher padding schemes, etc.

But no one cares about the other 17 courses, they just want me to have internalized a crazy level of detail on one in particular, as if I had studied nothing else for 4 years.

The performance problems I've been called on to solve, I solved by having a vague idea of what's going on at the OS and network level, something that apparently makes me a wizard at a company that allegedly selects for "CS fundamentals."
