I’ve worked with a couple people like this. They’ll come in bragging about their (actually) impressive résumé. There will be a honeymoon phase where everyone is convinced Mr. Fancy Résumé will change the world. A year or two will go by and everyone will realize they are the embodiment of capitalism. All confidence, importance and big talk on the outside, actually dumb and ineffective on the inside. Gilded, you could say. They get wind that their time may be up, quit, put their new badge on their résumé and starting fucking the next one. All that is to say there are a lot of people out there who are great at building a résumé, but not actually great at doing any work.
