It's true that our "PR1" (entry level professional) hires mostly come from our campus program, but that's an artifact of where and how we source, not that we wouldn't consider hiring a PR1 SWE from outside of campus. (Why would I possibly care whether we sourced someone at a career fair or from a response to a careers site posting?)

I do admit that I looked on our careers site for all SWE openings and we have no posted entry level roles. I'll ask the TA folks if we ever post PR1/SWE1 roles on the careers site, or if we get them exclusively from campus talent programs. (You have me genuinely curious now.)

Edit: checked with my talent acquisition head and she reports that we do sometimes post and hire PR1s from the careers site.
