Long hours and daily micromanaging. It gets a bit tiring constantly having to meet every single little thing they decide they want. Expectations change a lot. Especially when it comes to promotions it is flexible and depends on the team and person. There's no clear criteria that applies generally. They'll say "if you do X, we'll promote you to Y." You do X, exceed it even. No promotion. Oops we also need these other things (insert unrealistic expectation here).
