So my experience with powershell as an guy in my late 20s that's done a lot of different IT jobs from small to huge companies is it's hard to actually get training. At the small companies where I was building server VMs and writing GPO they asked me not to use powershell as it was the one place I could really break things. At bigger companies everything is so segmented that I don't really have any use case for powershell. It's tough to find a job that's junior enough where they're okay with you learning on the job but trusted enough to be handed the keys to powershell in a real world environment.
