There are high tier state schools and there are other lesser tier state schools (usually anything "XXX State", but not always!). But the number of high tier schools is around 30 in the US, so its not a very exclusive club, but once you come from outside that group, life can get very hard to get into a big company. But then, life doesn't completely suck, you can still get a job, especially if its at a local company that already has many employees from that school.
