It seems to me that this story has a bit of sensationalism in it? It doesn't mention the engineer's salary. At that kind of offer, I'm going to assume he's a super-star performer. So his salary is probably on the far right of the bell-curve. Also, how long is the vesting period? 5 years? 10 years? So that's a bonus of 350k to 700k per year? What if he was already making 350k a year? What if he was making 500k? If so, then 3.5M isn't that outrageous.
