I was part of a fun era at my university where they switched from C++, which is what I took in intro to programming, to java. So by the time I was doing some group projects senior year, I was working in C# with people who had only done Java.

They wanted to abstract everything. Everything had to be a class. Any time they repeated 2 lines of code it got put into a helper class.

We ran into an issue where the code just would not run no matter how hard we tried and of course no one on the project but me bothered to use git (they would literally send me the zipped up project on discord and I had to copy and paste everything into the actual code). I ended up rewriting the entire project overnight. It actually wasn't that bad once I got into the flow of things. Turns out none of them knew how to program without being explicitly told how.

Still not the worst college group project though. Maybe top 5.
