I have been working with a younger colleague doing just this. Résumé driven dev. Every week in the daily meeting, he just feeds us with an unknown API that no one had ever hear of. In the first week I was impressed but over time, I discovered painfully he did not know, almost all the time, the thing he was talking about. Usually I actually tried these new API but discovered latter, whenever I blocked on a technical aspect, that he had never actually used it.This shocked me... 7 month later we do our daily meeting, but no one really cares when his turn is on and he talks about a 'wonderfull new API' that 'do the job better... because we know he doesn't know what he is talking about. His resume is a wonderfull resume, but I discovered recently he had been working in my company as... à salesman. This clicked in my head, : resume driven dev is like salesman resume : Shines allright but don't expect to deliver.
