The above data is only of engineers hired using TripleByte platform. I saw only a handful of open positions with Apple.
The data is based on the type of companies uses the platform to hire which probably doesn't involve big paying companies such as Googles, FB, Uber etc
FAANGs all issue RSUs and cash bonuses but if you are a senior engineer doing good work you should expect your RSUs to match your salary in year 2-3 and exceed your base salary in years 3-4.
If you take their numbers that works out to $350-$400k.
