In the software development space, we tended to shy away from hiring certs, eg MCSD, etc. They proved to be a very poor substitute for experience. We had far better results in the IT space with certs like Cisco, and similar certs.
Even supplemental, they give a bad vibe. They're just so unusual to see on a developer's resume, and it's easy to conflate that with the bad candidates who only have certificates on their resume.
