Co-worker who blew you away with their technical skills?
I work at a startup and we hired a new grad a few months ago. This kid may lack experience but as far as his coding, design and architecture skills are concerned, he is better if not at par with staff and senior level engineers. It's almost awkward at times when he correctly identifies flaws in design of even architects who came from companies like Netflix and Facebook. I once asked him if he has tried to get into established companies like Google and he said he has no interest in joining those as he has already saved enough from his mobile apps to retire if he wants to.
Any similar stories?
Edit: one thing I forgot to mention is that he is only 26 but he started coding when he was 12 as his parents were also engineers and supported his passion from an early age. Not only is he really bright but also very down to earth and respectful without any hint of arrogance.
