From what I know talking to AMZN engineers, they still vest over 4 years, but you do not get a big chunk of it until year 3.

Probably still worthwhile when the $200k initial grant turns out to be worth 2-3X more after 4 years.

edit: typo

They do 20% over the first 2 years then 80% over the last 2.

Turns into a pretty big win for them. They get to keep a lot of stock from people who quit after a couple years, plus they can justify not giving you raises after year 2 because hey you are making enough already (with stock they already allocated to give you).

$200k ? My recruiter has screwed me then.

Last I saw (a long time ago, stock was <$100/share), the grants were $50K/4years ($2.5k/$7.5k/$20k/$20k)

I think that's still the target.
