Circa 2013 I was a tech conference attended by a contingent of RapGenius engineers. They were incredibly obnoxious. Loud, arrogant, boisterous, with no regard for anyone around them. This was when RG was getting a ton of hype and these engineers at least clearly let it get to their head. I distinctly remember one of them walking around in a t-shirt with "FUCK FUCK SWAG" printed on the front in huge letters.
Years later, through my wife, I became friendly with a high-level engineering manager at what had become Genius. Totally normal, down to earth guy. I liked him a lot. From talking to him, I got the impression that the company had "grown up" a lot. It was clear that they were very aware of the perception described above and were faintly embarrassed about it.
