I don't have any of the major certs. The best I can claim is stuff that I got from training courses on obsolete IBM networking systems and the like. I am not a big fan of most certs since they're often just collections of "gotcha"s and indicate no real competence. I threw down the
Java cert study guide in disgust when they got to the part on
asserts. I was a long-standing fan of asserting in C code before Java came out, but Java has an incredibly complex assertion system. That, so far as I've seen, absolutely nobody has ever used/ I don't even recall it being employed in the JVM source code, come to think of it.
If I ever feel the need for assertions in Java, I'll look it up and it probably will have changed from what I was supposed to memorize all those years ago. I have to reserve my memory for daily essentials. For the rest, as Sherlock Holmes once said, there's the lumber room of my library (or web searches).
Unfortunately, Human Resources departments like certs and diplomas because it provides an easy way to automate themselves out of actually screening candidates. Though just this week there has been quite a conversation about how that approach is depriving corporations of essential and valuable workers. I don't think I've ever obtained a job applying via HR myself.
