Theoretical computer science -- This is a branch of mathematics. Going into this basically means going into academia as a mathematician. It gets into the nature of what makes problems "hard" and how to quantify that. You'll skim the surface of it while getting a CS degree, probably, for maybe one class, in like your third year. Machine learning -- Hot field these days, can be very math heavy, but these days very accessible. Can involve basically any field, from gaming to agriculture. Stuff like generating realistic voices, self-driving cars, and automatically translating between human languages. Big systems engineering -- Stuff like AWS, or like Reddit, or Facebook. Taking programs and making them handle 10s of thousands of requests per second without falling over, and then making them fast. Mobile apps -- somebody's gotta make iPhone apps. Desktop apps -- Weirdly uncommon these days, but people do still write programs that run on PCs. Video game development -- Basically covers any and all of the other parts of computer science, but for half the pay. Embedded systems -- software needs to run your car or refrigerator or watch or toothbrush or whatever. Cryptography -- Like normal mathematics except you get to talk about spies a lot more. Computer Vision -- overlaps with machine learning these days, very cool stuff. Human Computer Interaction (HCI) -- Study how people interact with computers. Overlaps with User Interface Design. Making websites. These folks divide themselves into "frontend" (They make the stuff that the user can see -- HTML and CSS and JavaScript) and "backend" (They make the stuff on the server that handles incoming requests). Regular ol' Software Engineering -- the profession of making big programs and making changes to them over time without drowning in complexity. The meet and potatoes of programming jobs.

My default response is to tell you that it’s not worth it so that there is less competition for jobs lol. In all honesty though, it depends on what your goals/plans are. For example, I did my BS in CS and now I’m in my MS and plan on going all the way through to my PhD. So for me it’s worth it. More on reddit.com

TBH, getting your first job is going to be hell no matter what unless you know someone computers aren't going away anytime soon it's probably just rough right now. the market is tight all the way around I got an ME decent GPA, and it was hard to get my first one, but after the first, it gets easier. either cs or engineering, you will see kind of the same stuff More on reddit.com

"computer science" as a career is working at a university or research department somewhere and usually requires a masters or PhD. It usually requires good math skills.

The majority of people with a CS degree don't work as computer scientists, but instead go on to be software engineers somewhere. If the question is "is software engineering a good career choice?" Then the answer is yes. It might not earn as much as a doctor, lawyer, finance, but it earns more than most other professions and is a lot less stressful than the doctor/lawyer/finance route.

The math load of the course is entirely dependent on the university and syllabus. Whilst you might have to pass a calculus course, you'll almost certainly have to do a lot of discrete math, e.g. graph theory/algorithms and things.
