Those ranking are only relevant for grad school or for those looking for a faculty positions. None of the elements of ranking have much to do with undergraduate education. It’s all research productivity and research activity of faculty. There is nothing there about quality of undergrad education, undergraduate research opportunities, internships, job placement of undergraduates, etc.
I mean, it doesn’t even measure non-academic job placement for graduating PhD students, even though the majority of CS PhD are employed in industry, not academia.
