<p>School reputation will probably not help you very much for an engineering job/career, especially in the long run. All the engineers I have met have always told me that its all about experience, what you know, and what you can do.
On the other hand, going to a prestigious school can be an unexpected help if you decide to change out of engineering, or decide to go to grad school, and especially if you decide to go the banking/finance route.
Cal Poly gets many of the recruiters that also come to UCLA, for instance. Some employers even prefer Cal Poly grads because of the school’s reputation as a hands-on top engineering school. Oh and, as far as salary and employment goes, having a degree from the alma mater of your seniors (at your job), will probably have a bigger effect than anything else. So go to a school that graduates a lot of engineers! 
I would suggest that a brand name school is always the best option if you want to go there, and can afford it, because it gives you more options. But if you’re sure you want to be an engineer then don’t worry too much about it.</p>
