Why do people write ads like that anyway? That just sounds intimidating. I'm pretty good at what I do, but I'm not built to do it in some sort of reality show tournament.
Those who make the decision still have a full blown office with real walls and a door so won't be negatively affected. It's mostly pushed because the open office idea is cheaper and allows managers to see butts in seats. Studies show it's a bad idea but people talk about collaboration and whatnot as an excuse.
