As another anecdote, I applied to a job that I had a project that was much simpler than several of the things I had done in my past jobs. It was a job I know that I could almost do blindfolded, so to speak. But they would literally not even speak to me because I was missing a certification (a useless one, not some real certification like professional engineer or architect or whatever) that they were for whatever reason requiring. I even mentioned to the recruiter that I had had the certification but let it lapse because there was no reason to keep paying for it, and that I knew several people who had the certification that knew the language and area less than me. Didn't matter.
