I went to a state school, albeit R1 which has a lot more funding and therefore opportunities, but I believe every state flagship is R1 anyway. Actually this in state school was cheaper than some other in state schools that were considered party schools/easier academically. Were you recruited at a career fair? fangs always had a big presence at our biannual fairs and people I knew seemed to have no issues finding internships coast to coast.
I went to purdue so we had absolutely massive career fairs and I got my first CS internship at GAFAM through one. After that, it hasn't been hard getting interviews at the other ones.
