Review process take forever and is pointless. You are not directly involved in any negotiation for pay or advancement. Your supervisor discusses with you manager who discusses with their manager to determine your pay and advancement. Whenever you ask who you need to talk to it’s always “it’s above me, I don’t know.” In the end, you only get promotion based on time served instead of actual work done, quality, responsibility, and performance. This means that you’re better off not taking on any responsibility and to do as little as possible.
