That is profit, ie after the employee has been paid.

So the answer is they can afford to pay 300,000 more before the employee is too expensive (based on this comment anyway)

Well 299,999 :)

That's profit per employee, not revenue per employee. Revenue per employee is much larger, at least according to this website [0]:

Since that's profit, I would assume (based purely on the phrasing) that it's net of obligations like salaries.

Profit is after expenses, so employee can be $300k/yr more expensive before they are expensive to employ.

Its pretty much the same number. An L4 at Google makes $250k and an L5 makes 340k on average according to levels.fyi. My experience with countering Google offers would indicate these are a bit low.

Edit: Then you have to factor in the free breakfast/lunch/dinner, buses, electric car parking and the fact all my Google friends seem to rarely work > 40hrs per week.

That being said, all the 'grunt' work at Google is done by contractors, who are paid far less and while they get the free food they do without things like PTO and Sick time.
