If you've just graduated as a computer science major and if Programming is something you are interested in, Then you should try and focus on any one of these.
Data Scientist - Learn and specialise more in DSA based problems. Platforms like LeetCode can help you become a better competitive programmer with good tests over algorithm knowledge.
Web Development (Vue/React) - The world of web is immensely huge and has everything you need as far as you choose the right tool. Else it can get overwhelming sometimes.
App development (Native/PWA/Flutter) - There was a time when native app development was the only way to go but now that you have amazing hybrid app tools and PWA with regards to web development. I think it's safe to say learning web development can strike two goals in one shot.
UI/UX Design (Figma/Adobe XD) - If you've seen enough of boring UIs out there and would like to kick it up a notch, it would be a good start to study different design concepts like "Material design, neuromorphism, Flat design" and then play with it as you see fit.
API handling & Testing (Postman/Swagger/Php/Node/Laravel) - If you're to work for a company you would definitely need to handle the backend for their given frontend application. Being able to create - test and handle API is a good start. You might have heard the term "REST" in a lot of places, now is a good time to learn more about it.
Database/Backend services (Cloud services, Mongo, Redis etc) - Depending on the type of frontend you are working on, it's essential to choose the right backend to handle the flow within the application, else it would be a cumbersome work trying to deal with it.
AI/ML - To put it straight, AI and ML are definitely not on the easier domains with regards to the above mentioned titles. This takes a lot of patience, practice and effort to pull it through. If you do manage to pull it through then consider that there's nothing stopping you from getting you what you need in this domain.
AR/VR - If you haven't heard about the hype of Metaverse, NFT and what not. You are either living under a cave or you've become a wise person. None the less, dealing with AR/VR can be quite some fun if things tend to workd right. A good place to start would be modelling your 3D objects (Blender) and using AR tools like Google's ARcore.
Let me know what you think! Would love to know what you're pursuing right now and how it got started!
