Intel

Bragging rights to all your friends, notoriety, the feeling of joy you get from being part of something relevant and successful.

The benefits are great.

Lack of training to get you up to speed with their projects. Then they expect you to produce a high volume of work in a short amount of time with no training. You can't "google" how to do things at Intel because it's all cutting edge and confidential – so you can't get assistance online. The pay isn't as good as Microsoft. Managers rank employees via charts and graphs that don't tell the whole story. In an attempt to streamline/assembly-line employees and their productivity, they sacrifice trust. But perhaps this is just one of those things that makes all corporations have a bad rep.

Please have legitimate technical training ready before a new hire arrives. I had to train myself and then get complaints that I wasn't fast enough.

Also, the way management ranks people via overly simplistic means is stressful. They have specific numbers they use to rate you.
