Don't worry, the prestigious school I went to crushes you to the point of giving an inferiority complex, so at the end we all end up the same :)

Generally speaking, you won't be happy working at a place that puts too much value into a college or university's credentials.

Only if you're the only one that's not in the club. Else, it's just that: A club. And it works for some.

I have a pretty crummy education but I feel like it's really forced me to have a lot more drive in my career and as such I've been more successful (so far) than a lot of people I grew up with who went to much better schools.

I don't know if that's my personality or my past that's doing that though, perhaps if I went to a prestigious school I would be the same way and would be much more successful.

Don't sweat it. I'm making more mid career than all of the prestigious engineering schools listed a few threads below, and I have an MSEE from flyover school. Just concentrate on something you enjoy, get good at it, and you will do fine.
