You haven’t seen LinkedIn cringe until you’ve worked in sales or sales adjacent positions. The amount of of hubris some of these people have is incredible
LinkedIn cringe is arguably worse in non-sales areas. Salespeople understand they're in the Matrix. Non-salespeople don't realize they're sucked up into this awkward world.
I don't consider myself to be particularly cynical, which is why it surprises me that I cannot shake off the loss of respect I feel for people I once respected after I see one of their linkedin posts on the odd day in the odd month that I do log in.
