Companies recruit at schools outside the top 30. There are 3000 colleges in the US. Do you think kids that go to the 2970 colleges that are not in the top 30 don’t get jobs? I’m not telling you not to try for some top schools, but you need to understand that it’s not the end of the world if you don’t get into one and end up at one of your safeties. You will find bright and curious people at all colleges, though you may need to look a bit harder if you’re at a lower ranked school.
