No, I'm pretty sure it's true. I had to spend a ton of time explaining what I did and its values to my managers, like writing "ELI5" docs and then suddenly when they "got it" they paid very close attention to my work, and formed a team around me and established scope and got headcount.
This is the messaging I got every single quarter:
"""David, your work is very good. All the people you work with say you're great and it's clear you are adding value, but you need to spend more time finding metrics that demonstrate that value and improving those. Also, if you want to get higher ratings, here is a whole bunch of extra management work and document-writing to do. If you do that, we can make a case for Exceeds and eventually a promotion"""
What I concluded was that I was better as an L6 than an L7 (L7 at google has a lot more responsibility, and far fewer job opptys) and I knew the value I was adding to the company without having to spend weeks cooking up metrics dashboards.
At google you're not going to be fired, if you're an FTE, with anything less than 6-9 months of feedback and runway to get back in the air (few exceptions)
