Half my current team at a well-known company doesn't even have CS degrees. The youngest one never went to college, but he's one of the smartest members of our team. I was recently hired, and I'm in my 40s and there's another guy who's older than me. My boss was a high school teacher, and he was one of the instrumental programmers in the entire company for the last several years.
Over the last several years, I've been intimately involved in hiring, and I can tell you straight up that no one looks at schools, and anyone who has half a chance at passing a phone screen will get a call. People might get more excited if they have a good name on the resume, but we called everyone that seems like a decent candidate.
