It's especially common when they used to work at a "famous" company. Some real world examples: in the mid-2000s being a "Googler" was a straight pass by some to thinking you were some wizz-bang amazing programmer. Because Google only hired the best and brightest, right? Then you work with some of them and realize they they were nothing more than a smart college kid who got lucky with who hired them and were terrible programmers. They were juniors at best, but now with the ego of RMS. The same happened for a while with "Game Producers" from Zynga, when they were riding high and had a better reputation. The trouble was that Zynga had a policy of rapid promotion so you got "Producers" and "Studio Leads" who couldn't last 5 minutes outside of Zynga. That wasn't always the case, but it happened enough that it actually became something of a black mark in the industry.
