As someone who holds a certification as an AEM Business Solutions Specialist (possibly lapsed by now) I have to agree. It's hot garbage.
I advised him to do AEM certifications. He did and then contract recruiters has started to flood him. He collects tons of cash as independent AEM consultant now. And with Java, he does "fulfilling" Java stuff on the side.
The boss doesn't know what content management even is, but they have heard of Photoshop and Acrobat so AEM must be good.
At least it's tolerable at all compared to the shitshow that is AEM.
just an example of the kind of companies that use it. apple, intel,etc .e.g https://jobs.apple.com/en-in/details/200207733/aem-engineer
