This will not apply to all companies, but for our hiring decisions certs have an adverse effect. If someone puts many certifications on their resume my expectations are lower and I likely won't consider them for interviews. It's a negative signal in my experience. Your time is better spent working on side projects, contributing to open source, writing a blog, etc. I.e. do real-world stuff instead of wasting time on artificial tests that require memorization and exist largely as a revenue stream for certification providers.
