Microsoft, who has owned LinkedIn since 2016, has recently been making headlines because recently they fired a lot of their engineers and QA staff and are now essentially vibecoding huge chunks of their enterprise.
What's more, Microsoft never paid the really big bucks like the FAANG companies, and so it's more or less an open secret that at the height of the tech hiring frenzy Microsoft had to fight for B-tier engineers that weren't good enough to work at e.g. Apple.
So, it's been 10 years, which is long enough for that trademark Microsoft mediocrity to seep into LinkedIn. And they're probably vibe coding everything. That's how you get to gigs.
