Google

Very friendly culture, incredible access to practically all company information, great people to work with and learn from.

With thousands of users every second, almost nothing is trivial, so work tends to never be boring.

The work process is very professional.

Of course, just getting to build stuff on Google's awesome infrastructure (both hw and sw) might also be considered interesting :)

Well, my salary is not particularly high.

Some of the perks listed are just subsidized, and some are not even that.

Also, there seems to be a slight trend toward money-oriented decision-making, slowly eroding Google's 'Googliness' factor.

Given the inflow of cash, saving a few million bucks should not be a priority over employee satisfaction.
