Some people may (and clearly do thrive) in such environments but I personally did not.
This particular scenario was a simplified excerpt but very well captures my perceived experience. Having to write a design for for something that was a solved problem (by a team maintaining a framework) felt like pure busy work.
If there was a higher meaning to this process this higher meaning (other than looking good / getting promoted) was not communicated in any effective manner.
Maybe I'm dis-illusioned with the current culture in big-tech but a promotion should be a result of doing good work, not doing work that is designed to look good.
And yes I understand that some of these mechanisms may exist to provide employees a clearer path for ascending the corporate ladder.
