CSCareerQuestions

While it's not exactly what you are asking for, I can try to answer this from PoV of someone who does have a CS degree (SW engineering bachelors, and then masters in game development and graphics).

What I've slowly started to realize over the (few) years working in the field out of school, the best thing that college gave me (aside from friends from the industry, which is especially important in gamedev) is not some concrete in-depth skill with so-and so language that I've been taught. I honestly don't remember most of what I've been learning, I've already forgotten and would have to re-learn most of what I've been taught, especially in the maths and algorithm department, and even though I've had several in-depth courses on C, I'd probably still have to google basic syntax since I haven't used the language for several years.

I've always kind of though that the school has not given me much, because of that. That I still have to re-learn things, even those I've passed with flying colors at, and I wasn't sure whether it was worth it.

But then I started realizing something - compared to other colleagues who didn't have a degree, I was usually the one coming up with solutions we could start investigating, when we were dealing with a more difficult problem, or when someone needed something written in a specific language they donť know (which happens a lot in cybersecurity), they usually came to me, and I was able to do it relatively quickly.

Why? Because while it's true that I don't remember implementation details or syntax of most of what I've been taught, I was forced to sit through hours of different algorithms and approaches for all kinds of problems, and I was forced to learn at least for that one lesson programming languages of very different flavours. Languages I disregarded as not relevant - but what I didn't realize is that the goal wasn't to teach me the language, but to introduce me to the overall concept the language is going for. Will I ever need Lisp, Phyro or Prolog? Probably not, but now when I see a language that works like Prolog or Smalltalk, I don't have to struggle with not understading what the language syntax is going for - because I subconsciously recognize the concteps, and can pick up any similar language without issue. I've eventually realized that thanks to college I'm not a "C# programmer", but I'm "a programmer" and so far I haven't encountered a language I would have trouble with writing anything i needed in a reasonably short amount of time and without greater struggles. Because for all of them I've already been through hours of working in a language that works in a very similar fashion.

I mean, trying to write something in a language that works like Prolog, without ever seeing it before, would probably be hell, just like it was in school. But now I'm vaguely familliar with that class of languages, and I don't have any issue with it.

And that's something that's really usefull, an would be hard to pick up on your own. Because I did went through a lot of vastly different languages at school, most of which I'd never touch. And you would think that you'll probably never need to know some obscure class of languages - until you find an RCE on ancient server during pentest that executes COBOL, and you really need that reverse shell.

And the same can be said for algorithms. I'd probably still take me way longer to write some of the more advanced sorting algorithms from memory than just googling for it, and I'd probably have to invent the wheel anyway, but I still vaguely remember they exist. Data structures are really important for this, because they can make a huge difference and there's such a large variety of them, each one being really good for some kinds of problems, but not for others. And the same goes for some general math stuff like FFT and various compression algorithms - I remember the basic idea vaguely enough so that they pop into my mind when a problem sounds similar to what it solves, so I then know what to research and rediscover whether it's really a good fit.

And this has been especially important in rendering, because it's suprising how many game developers have no idea how exactly does rendering work, because they never had to learn.

I've been through classes on low-level rendering, and I don't remember almost anything as far as concrete math is considered, but I do have a lasting overview of vague memories of the steps included and the general idea behind it, and that's enough to jump into unknown shader code no-one has any idea how to fix, and start noticing concepts I vaguely remember being taught, and can make changes for which I can guess what will it impact. And the same concept also applies to UML diagrams and other bullshit. Sometimes you encounter one in the wild when dealing with documentation, and it really helps that I kind of understand what it's trying to tell.

And that's all thanks to classes I mostly considered useless - because classes on languages I use daily haven't really taught me much I didn't know already, and that's why i felt like the school isn't worth it at the time - I'm learning nothing new, and have to waste my time with many more useless bullshit that I did begrudgingly passed.

Turns out the useless classes are what have given me the most, without me realizing it. They have given me a very broad overview and experience with stuff I'd never learn on my own, and it made it vastly easier to research and learn stuff I ocasionally need - because I already have some basic experience in that kind of problem, even though I don't really notice it consciously.
