Where I live, certifications are the bread and butter of secondment agencies. Since their customers typically have little knowledge of IT, they need proof that the human beings they provide are, in fact, programmers, so they push their employees through yearly (and expensive) courses to get their paperwork up-to-date.
As a result, I’ve always looked down on certifications. I worked through the Java Certified Developer coursework early in my career, and decided it was a good source of information if you had the ambition to become a compiler, but offered little extra to someone with a degree in software engineering.
There are many strong opinions I developed in my twenties that are worthy of re-evaluation, and maybe this is one of them.
