@CaliCSEngineer I’m a semi-recent Asian American Grad from Cal Poly. I think a previous thread of mine will answer many of your questions.

Quick answer though:
CS at CP is more industry based and UCI is more research based, huge difference comes down to the number of lab classes, hands on action, and much smaller class sizes (400 vs like 30).
Currently at Columbia in NY (previously at Apple) and, essentially, general consensus is no one cares about differences bw small universities (If you’re not UCLA, UCB, Stanford - all other California Universities are basically nominal in difference). CP is closer to Silicon Valley so more jobs. UCI will have more research.
