Doing languages in university - what should I do to have better employability?

I’m an Italian 21 yo in my first year of university in UCD, Dublin, majoring in languages (Spanish and Portuguese). While I am certain that studying abroad at a pretty well-known university is something at least a bit impressive for any employer, I’m super worried that after all the sacrifices and money spent to study abroad I will struggle to find jobs. I’m considering maybe doing some volunteering teaching English abroad but in general I guess what I’m asking is: what I could I do to improve my employability? I def want to learn a fifth language (Norwegian) because my goal is to move to Norway at some point and I already know a tiny bit of the language, but although I’ve just started uni I’m a bit worried about the job prospects. Any advice?
