Not really. As an industry, computer science is still pretty young and disorganized. Dynamic, ever-changing. There are tests - the silly interview questions you see, QuickSort, A* algorithm, trees.. And as a practitioner, there are some standard tropes which vary over the years and areas of specialization, like writing your own blogging software, a basic back-propagation neural network, or completing the Advent of Code exercises. But I think for your position, as someone eager to learn and show his growth, you should just pick a project that is interesting to you and somewhat challenging and do your best at it. By publishing the work you will say "I completed this" and be able to show it as a badge of your skills. All the better if you "kill it" and produce something better than what has existed before. And above all, congrats on your exciting transition into programming. It's a challenging and important field.
