I guess some people like it and some will hate it.

Depends on personality and project I guess.

Actually that's not entirely true. There's one manager in my current project, joined as experienced analyst, made manager in 3 years. Im not directly under her but working together and she indeed is really good.

But, they don't always get it right I'm afraid to say. Some really good people didn't get promoted after performing really well a few years running and eventually left.

It really all depends on luck and how you set yourself up to succeed. No where is perfect after all.

Accenture bonus is just so so.. Nothing great.

But where it's great is the promotion, the jump is quite huge everytime you get promoted. That's how they motivate people to work harder and to aim for promo.
