Sometimes and in the real world, yes, it helped me 1 month ago to get a job. But, maybe not in reddit bubble. I have less than 1,5 yoe and the company who hired me had one data analyst that leave for another company and they use tableau and oracle database. They are migrating to the azure/powerbi and the people who work in the company does not know much about azure. They pay a consulting company to help them to migrate to Fabric, yes, fabric. They needed a person who are INTERESTED in learn and help them, so, when i told i have DP-900 the manager asked for the cert (maybe to show the above manager). It of course demonstrated my interested in cloud and combined with my experience with power bi, totally worth it. If you are trying to enter in a consultant company, or a high tech company, maybe is not sufficient, otherwise, if you are trying to enter in the real job market, is a nice cert to have.

Try John Savill's whiteboard cram on DP 900, on his Youtube channel. It's not intended to pass the course, its a logical representation of what's in the exam and how the Azure infrastructure works. The video is ca. 60mins. After watching that you'll probably know if you have the knowledge already. And if you don't where to study. More on reddit.com

900 is the first step, so great to hear you can check that off. How many hours would you estimate you studied? More on reddit.com

I used a udemy course and ms learn, I prepared for about 2-3 weeks . My advice is finish the videos, do other practice exams maybe ,and then just do the exam, you can never really feel prepared . More on reddit.com
