Build stuff
We have a nearby state university with a so-so computer science program. 2-3 graduates every year go to FAANG, a handful go to the local fortune 1000 companies, and we (a They all list C, C++, .NET, HTML, CSS, and Java on their resumes but haven't done anything except a simple group project in any of them, half the time not even writing any code for the project. Which means a role in documentation, testing, etc.They come with a chip on their shoulder, flaunt their degree, and demand a salary close to what they think they should be getting, according to their advisers or statistics or whatever.To make it worse, they don't have any personal projects to show. I tell every single person that I interview to create something, even if it's a failure. At least you can come back and discuss your experience trying to create something, and you'll learn more about development working on that project than you did the whole semester you learned Java.
