I spent 12 years at LinkedIn. Sadly, it's not even close to the engineering org it used to be. The era where Kevin Scott led engineering was a really good one in comparison.
They seem to be trying to jam AI into a bunch of things now.
As an aside, I work on a product that should be considered feature complete, but PMs keep dreaming up features so they can get promoted. I wish we could just take some time to clean up the horrendous tech debt accrued over the past 10 years of feature proliferation.
IMO more about growth of the engineering teams that lead to any specific culture deteriorating.
