In a recent post, DHH (David Heinemeier Hansson of 37signals, creator of Rails) voiced his opinion on asking for years of experience in job postings for programmers:
Requiring X years of experience on platform Y in your job posting is, well, ignorant. As long as applicants have 6 months to a year of experience, consider it a moot point for comparison. Focus on other things instead that’ll make much more of a difference. Platform experience is merely a baseline, not a differentiator of real importance.
