Your comments are based on a handful of FAANG companies. PIP didn't exist and doesn't exist in most places now. The three months probation allows an employer to let someone go without notice. If they are let go within a year 2 weeks are owed.
I'm not worried about big Faangs spending millions on bad hires so logically they have to spend tens of millions on a hiring process that bleeds money and produces not great results. They play this game where they push back stock grants to the last years of a 4 year vest and offer a low base rate. That first year isn't costing them much and with an average of less than 2 years of employment (Amazon) it becomes a profit center.
You would think a faang should be able to find the best people the easiest but they struggle more than a smaller shop.
