I'm also curious about that. I'm just starting out in industry and am confused if most people are expected to do that. Do future recruiters go through your old linkedin posts for stuff like this? Or is it just a general update for their personal circle - basically the corporate version of instagram stories.
It's just people being happy about something that's happened for them. Given how capricious a company like Amazon is, though, the professional speech is probably to avoid giving Amazon a different reason to complain.
It's gonna be a different situation for someone taking their first programming job out of college, and someone who's been doing it for long enough that they don't care (and would probably fire a company like Amazon before being fired themselves).
Recruiters won't even read my programming languages. I have gone to so many interviews where they didn't even check that the skills they wanted were on my resume.
