Google

First of all, I have infinite respect for the founders, their ethics, the kind of culture they infused in the company, and the continuous (positive) influence that they have on how it's operated.

I also deeply admire Eric Schmidt, both as a motivator and as the provider of a very strong vision and leadership.

The openness, the infinite possibilities for feedback, and the attitude to listening to that feedback and trying to convert it into ameliorative actions are something that makes me think I wouldn't work anywhere else.

Of course, no company is perfect, but frankly, I have a hard time trying to imagine a company working better than this one, at least for what concerns employee lifestyle, work-life balance, career possibilities, open communication, etc.

Sometimes it seems that the company loses sight of some of its activities, which results in duplication and scarce integration of efforts.

Also, not everything is "interesting cutting edge technological work" at Google. Sometimes very smart people have to do very boring jobs, because the areas that bring the higher income are also the most established, less innovative, and most "traditional" in terms of what kind of work activities they need.

Sometimes a part of engineering management seems more interested in low-value formal things (such as enforcing readability and code conventions) than in providing a great unifying vision for our products.
