I attended both UCLA and USC, volunteered extensively within each of their healthcare systems, had the grades to be competitive and didn't get interviewed at either. They don't favor IS students, but because of the overwhelming number of in-state apps, they tend to have high class percentage.
For rule of thumb, avoid state schools if you don't have significant ties to the state or exceed the requirements of their core mission. So rule out, UCSF, UW, OHSU, FSU, UF, UWSMPH, CU, UCR, UCincy, UH-Burns, FIU... and i'm sure there are others.
