I've been a PM in a few B2B companies, and the reality of the job was never even close to the ad, i.e. we (PMs) never had authority over either Engineering or Marketing.
"Product-led" is today's buzzword, but I'd have to personally experience it before I believe it.
Yeah, IMO "product-led" is just something that sounds nice when you package it up with a bunch of truisms and sell it as a consultant. There's a nice little industrial complex of consultants, "coaches", and other thought leaders who haven't shipped any product in a decade or more but will gladly sell you their silly services.
We're just here to do a job like anyone else, with hopefully a reasonable area of accountability. The thing that "drives" a particular initiative is what matters the most at the time - could be a big marketing push, engineering quality push, something we know sells well into enterprise markets, etc. It's fine.
