Have had two since I started at the place I'm at now. It's basically very nebulous "you're doing ok/you're not doing well in x" type reviews that they get from the departments you're contracted out too. Recommendations are usually "keep doing what you're doing/do more work/do work faster". You provide feedback forms for how you feel youre doing in various areas, but they're effectively useless as its the managers rebuttal that holds all the weight. There's rumours of career planning being integrated into the mix, but that's apparently been on the table for years with no change.
Had an associate of mine at the same company two weeks ago get a performance review (more of a contract since he had to sign it), that said he had to improve performance in a month or he'd be fired. The reasons? Too slow/too low quality, but no specific measurable metrics to meet that he'd be able to use to keep his job when re-evaluation comes up in a month.
Needless to say, performance evaluations aren't given a lot of thought here. Wish they were.
