> “encouraging harsh feedback” and subjecting workers to “intense and awkward” real-time 360s
... I can't help but think how much a review there sounds like a capitalist version of a Maoist "struggle session" (see https://en.wikipedia.org/wiki/Struggle_session).
The point of a struggle session wasn't to build people up; it was to tear them down. A culture where the way you move up is by tearing your colleagues down is generally a dysfunctional culture. Everybody involved ends up losing sight of things outside their four walls (such as, you know, what customers want), because they're spending all their time squaring off against each other internally.
I would suggest a healthier, more sustainable culture could be imagined by contemplating these words from the Tao Te Ching (Stephen Mitchell translation, chapter 27: http://taoteching.org.uk/index.php?c=27&a=Stephen+Mitchell):
What is a good man but a bad man's teacher?
What is a bad man but a good man's job?
