Yes in most while others have reliable information from multiple close colleagues. Also don't get me wrong, it is great experience to be part of any of these leading high-tech companies in relative to the most other ones, so my comparison is relative btw top ones.

I doubt it, considering their point about Amazon (the RSU backloading, not the hire-to-fire thing) is a misconception that only someone who has never worked at Amazon would complain about.

(probably some of the others too, but I only personally know about Amazon)

At two years per that's only twelve years worth of experience.
