LUL! Those are amateur numbers, buddy. I do 11-6 maybe, and work at a big 5 tech company making big 5 tech company salaries. And frankly, we aren't working a lot of the time during the day either.
And yes, we have the "unlimited" vacation, which usually results in people taking about 4 weeks a year, on average.
I think people underestimate how easy it is to work at some of the big tech companies.
