/not a MSFT employee - but that's how my MSFT friends describe it
However it is neither fun nor productive. The majority of the official classifications are mismatched and/or inapplicable (but nevertheless required hoops to jump through), and getting any change approved requires heaps of paperwork. About this time last year I threatened to quit with an offer letter in hand from a startup; my company promised to match my salary to the offer. A year later, I'm only just now getting the rest of the raise and promotion, because of the skill qualifications, achievements, etc. that we had to get filed and approved.
That certainly makes me feel happy about the “gamification” of my industry.
