I've only been at one place that had OKR's. That was my shortest job due to the toxic work environment. OKR's are simple enablers of toxic environments due to the amount of goal post moving and gaslighting.

"Here is an arbitrary goal """you""" agreed to, why has it not been achieved?"

"Well, you didn't really give me a choice and you also moved me to another project or the project was killed off"

"not good enough"

Yeah, I'll pass anywhere that encourages this.
