Really? That’s quite surprising; I would expect all of them to have some sort of “programming languages” course or similar…what classes do they have then?
I’m a math student minoring in CS and I covered all of that before I’d finished second year. I also covered functional programming in first year.
I’m really surprised your CS degree didn’t cover operating systems, compilers, or algorithms. CS students at my school are required to take all of that stuff (and a lot more, including everything you’ve mentioned) before they even finish 3rd year. In 4th year they’ll be studying things like networking, real-time programming, computer graphics (physically-based rendering), machine learning, and computational math (for simulations, numerical solvers, linear and nonlinear optimization, etc).
Ah yes, operating systems - file that under "I forget what else".
Like I said, I feel that I overpaid for that education. The degree itself has paid for itself many times over, but I needed to learn basically everything important for a CS career on my own.
There simply aren't enough professors to maintain that breadth of courses in those departments.
