10-20% seems really low in my experience. Do you mainly hire out of the industry?
Hiring heavily from colleges results in 60%+ of applicants that somehow have a B.Sc. from a university that produces amazing applicants with great (3.5+) GPA's but stall at either fizzbuzz or (just in case they memorized fizzbuzz) i-can't-believe-it's-not-fizzbuzz.
Furthermore, some candidates (20ish percent?) can't even answer basic, non-trivia questions about their language they self-report to know best. e.g. Java programmers who either don't know or cannot articulate what the static keyword does.
I'm convinced there's a path through every university, no matter how good, where you can avoid all the good professors and only pick babysitter professors and squeak through your four years with a piece of paper and a well-tuned sensor for which profs actually grade homework instead of just giving 100's so people don't complain.
