>>9448998It's kinda difficult to figure out what you like without the experience, I went into my first job pretty clueless about all of that. In school I'd suggest you just take your CS classes and see if there are security related electives that you can take as well. For Data science stuff I'd look into Python because a lot of data scientists use it, it's got a lot of very mature libraries, and it's quick to pick up. For security, I'd suggest just lots of research, there are cool sites out there that test out your hacking skills, and those are usually a good start to security, because basically most security experts are just good guy hackers.
Your best bet for a first job would probably be just a general position where you'd be doing regular coding, but where there's an opportunity to grow into security or data science related positions. If you end up with a good boss, you can let them know your aspirations and they'll do their best to accommodate you and give you tasks that relate to what you're interested in. If you end up with a bad boss or one who doesn't care that much, then refining your skills through certifications and stuff like that is always helpful
Hope some of that advice was helpful. Not too knowledgeable on the data sciences side unfortunately
