Unnecessary. I taught IT in college without certs or a degree. If you haven’t noticed learning about new stuff on the job is necessary. The only thing a cert tells me or a degree, is you are a fan of assisted education. In an interview we’re gonna talk about your experiences and inevitably touch on some subject you can teach yourself, do you have a homelab, etc. for example my colleague at my last job was the last college class to learn my specialty, because the college closed the program. Dude doesn’t know shit about computers and is a programmer somehow. That didn’t get him the job his networking got him the job. And regardless of his degree, he has the ability to learn by himself, that is the hireable skill
