Earlier quoted context omitted.
That's ironic then, because a huge percentage of the full-time employees at FAANG are actually former contractors who've been converted. So that would suggest a large chunk of their full-time employees are sub-par. And that still doesn't answer the question--why hire anybody directly at all? If you're so much better than the other contractors, they could just pay you higher rates. It'd be the same thing.
"huge percentage".. got any numbers to back that up? i can tell you its a single digit percent at G.
You basically get to pick and choose who to hire after a year of seeing their code. Bonus if you pay contractors really high rates to attract good talent.
