I am familiar with Berlin rates and this person is right. 400 USD (337 euros) an hour is unrealistic, unless you are hiring Cure53 specifically because employee X did groundbreaking research on topic Y and that's why you need that expertise; only then would I expect Mozilla to agree to that sort of rate. The range is more likely to be 110 - 250 euros per hour, where both ends are fairly unlikely but it's not as if I have comprehensive industry-wide data on everyone's financials. (I'm not that kind of hacker, heh.) The sibling commenters are right, though, that the hourly rates charged by the company are not very related to how much you earn as a person. I wish I got my hourly rate as salary, but I see what kind of organisational crap the founder has to do and it's just not worth the headache to me.
