As for Netflix, they do give you option of choosing to split your salary every year i.e all cash, all options, some cash and some options as you see fit.
This depends on the company. My understanding is that Amazon does keep stock price in mind when doing vesting of stock. If your personal projected comp is above the "intended" level (due to a large share price increase), your stock award in a given year will be smaller.
So your stock vest in year 3 might be smaller because growth was high (or your initial offer was above-market). Google and Facebook don't do this. Each year is modeled independently. Microsoft also models years independently afaik, but their stock vests slightly differently.
I asked for X comp, say 100K total for 4 years, including stock. The recruiter calls me back, says she got the total I wanted, I write down the numbers and it totals to 90K. I ask her why the math does not check out and the answer was that the 'missing' 10K is the projected stock growth.
Haven't seen anything like that in other negotiations.
Or is it still competitive without taking such appreciation into account?
Please correct me if I am wrong here.
