I had a great experience at Unisinos and the campus in Sao Leopoldo is a huge highlight, it feels more like a park than a traditional university actually. The tech labs and the main library have everything you need, which made a huge difference during my studies. The infrastructure there is easily one of the best parts.
Most professors are highly qualified and bring solid market experience, which is great for networking. A few theoretical classes felt a bit slow but that happens anywhere. Its a big investment but worth it for the weight it adds to your resume.
