As for the so called "college experience", it depends on how social you are and how lucky you get. If you meet the right people, I'd assume you'll have a blast. If not, then you're probably going to spend most of your time alone.
As for work and assignments, it depends on what you're majoring in. If you're going to go into science, get ready for a relatively big workload and labs. If you're going into business, there's the stereotype that it's one of the lightest majors out there and people I've talked with in business seem to have a light workload too. If you're going to get into engineering, forget about grades lol.
The stress portion of it depends on how organized you are imo. For me, I won't say I have a ton of assignments, but if I don't stay on top of them, it'll pile up pretty quickly
Also, working while studying can be manageable but it depends on how many courses you're taking. A full course load and working would be extremely difficult, but taking a lighter course load while working is manageable.
Anyways, I'm only in my first year so take what I say with a grain of salt lol
