hate them
what a total waste of time. Embarrassing. Hurtful. Stressful. Darwinian. Only the most persuasive survive. Large employers only run them to quantify who to lay off with some data that they think can stand up in a tribunal. No other reason. Same for 'objectives'. If you do your job and your manager is happy there doesn't need to be anything else. Its when your manager isn't happy that they want data to kill you with.
