My husband and oldest son are both chemEs and both have worked for top global chemical companies. Ds graduated in 2011 from a small public tech university. He cooped, was interviewed and made offers by companies that hire equally from top 30 engineering schools. (Can’t say either of them have ever worked with an Ivy grad, but I wonder how many Ivy grads fit in plants?) My husband has worked alongside top engineering school grads his entire career. His corporation is just as likely to hire from a well respected local university in any given location as recruiting on larger top university campuses.
