A) usually if you're fresh out of school they filter on your school name because the average MIT cs grad is most likely better than the average cs grad from university of kentucky.
B) if you have work experience, they filter on where you worked because the average google engineer / HFT engineer is probably better than your average engineer who works at missouri national bank.
C) if you've done something great that everyone knows about (like being the author of popular libraries, inventing tools that people use), then you can most likely bypass filters A and B if you can get in touch with a human recruiter (shouldn't be too hard).
For prestigious smaller companies which gets a lot of applicants, there is no easy way to reduce the pool without doing A and B. It is unfair and what college you go to might depend on circumstances beyond your control but if you have high ability regardless of what school you went to, you would eventually do B or C and get into the prestigious company.
If you don't have high ability and will never do either B or C, then they did the right thing filtering out your resume.
In the real world, it doesn't make sense for a company to discriminate against a candidate with higher ability just because they went to the wrong school (unless the company makes money from appearances like law firms, consulting firms or is corrupt and entrenched).
