I had a recruiter on LinkedIn reach out recently who sent me a PDF of a job that they thought I might be interested in. I read through it, and the job seemed fine, but on the very bottom it said "people who went to a mediocre school need not apply".
I could kind of understand this if it was a junior position since the incoming person might not have any real experience, but this was for a staff level and required at least ten years of experience.
I responded back to the recruiter with something like "I didn't go to a fancy school, and I don't want to work with these assholes if they think that that's more important then fifteen years of experience. I'm not sure why you sent this to me, you can see my education history clearly on my LinkedIn profile".
