I joined Amazon as a new grad. Signing bonus was part of the standard new grad offer.

> People paying bonuses for new grads is a sunk opportunity cost

Sure but FAAMG aren't really trying to pinch pennies. Signing bonuses also usually have a clause where you have to return it, if you don't at least stay a year. Signing bonus as a new grad is a HUGE help to the new grad. When you're competing between FAAMNG, that signing bonus can sway what offer a new grad would accept.

> google (does give signing bonuses)

I'm currently at Google but I had to negotiate the signing bonus. It wasn't part of my original offer.

> People who jump company to company...

They absolutely do.
