One more: abstract cultural onboarding
This involves spending days to learn a lot about very abstract culture and values like being dynamic and innovative, and inclusive.
Usually also in stark contrast to actual practices. Like spending 2 days on DEI training in an office full of white 20-30 year old men, and the three token woman they hired all still in junior roles after 5 years of service.
Not sure what this part of the onboarding is about but many companies do it to a degree. It doesn’t seem useful to anyone or impacting anything in the actual culture.
