Traditional CS is not in vogue at ex-USSR universities. Poring over type systems and pure functions just never caught up over here, compared to good old Knuth-worth "close to metal" CS.
Some SDEs do take interest in these topics independently, though.
I sometimes feel sad about one particular branch of study, which could be applied to speed up computers, which was active right when the USSR was collapsing. Konstantin Likharev, among others, from Moscow State University worked on Josephson junction logical gates which demonstrated - then, 30 years ago - switching frequencies which are still out of reach for at least the mainstream CPUs (in some hundreds of gigahertz). A bit hard to find good articles about that research today - this one, https://www.beilstein-journals.org/bjnano/articles/8/269 , is an example. I've heard it failed to produce a commercial product because it was really hard to miniaturize.
Data structures, low-level workings of CPU and other hardware, computational compexities, binary algebra, combinatorics and discrete maths. Throw in some logic circuits design.
The same things they ask on FAANG interviews, coincidentally.
It seems very similar to what we study in "Computer Science and Engineering" in Italy, which is a different degree from "Computer Science". The former is considered engineering, the latter isn't (pretty strange tbh, but that's how it works)
Ya, I second guessed myself. First in, then I thought "Naw, some pendant will say 'ackewlwally, that's software engineering'". Next time, I promise to take the principled stand.
