We have something like that in the company I work in. There is a competence manager, someone from HR, who follows you through your career. He/she talks with your clients, gives you feedback, arranges trainings and so on. Once a year, there is an interview that is quite similar to the stay interview. It happens before the annual review, so we're not discussing pay rates.

I believe such an interview should not be done during the annual review, as the only thing you will be focussing on will be: "Come on, come on, just tell me how much raise I will get". 🙂
