I think you have to visit to decide and you haven’t.
UCI is more a go home weekend type environment - it was when I grew up (In San Diego) and the zillions of comments on it today on this board shows it hasn’t changed.
Internships and students happen from the student, moreso than the school.
As you mentioned Cornell, it’s students find jobs on linkedin, indeed, company websites far more than any other way. Of 85 students (39 reported), the “how” they found jobs, 3 found jobs via the career fair and one through on campus interviewing. This is very consistent with my son’s experience at a lower pedigree school than you are looking at - had 20 interviews, all from indeed (didn’t like who came to the career fair, etc.) with 5 offers by xmas and a 6th from his intern company.
That said, I’m using Cornell as an example because they show the source of how kids find jobs - but no reason to consider WL schools, so get it out of your mind.
It’s a new world today - and any school you mentioned will provide you a solid basis toward employment (assuming the economy, for engineers, stays robust)…most ABET schools in general will so if cost matter (you noted), find your most affordable.
Yes, have an idea from calculators for UCs. Have not done it for Purdue. Not sure about Purdue, with Out of State factor. But hoping Net out pocket will be similar. Not sure.
