Pros
I worked for Google 3 times as a contractor before converting to full time employment. The perks are amazing and can't be beat. Almost all the cafes are top notch and the microkitches are fully stocked. During my time there, I met some of the most powerful people in the world, was entertained by some of the greatest bands and met some of my favorite authors. The annual holiday party is also exceptional and no cost seems to be spared.
Cons
1. Work/life balance is non-existent 2. The recruiting organization is very metrics driven 3. Very political You're expected to hire an ungodly amount of people AND work on high profile projects or your quarterly performance review could be in jeopardy. The keyword is "high profile." Unfortunately they don't often tell you if the project you're working on is high profile enough until it's too late. Keep in mind that sometimes your projects carry more weight than your core job. On the political side, friends of managers were promoted (so were their significant others) ahead of people many thought were far more qualified. One case was so blatant that I wondered why no one said anything. Very senior management did a good job of conveying the overall message but many middle managers were incompetent. One former manager frequently brought coworkers to tears. One new manager told me shuttle time wasn't work time. When I explained I had to work on the shuttle so I could make it on time to pick up my daughter from daycare at 6:30 PM, I was told "not my problem." Keep in mind I was working 9-10 hours a day from the time the shuttle picked me up in the morning to the time it dropped me off at night. Yet I was dinged for not being at my desk for that long because I couldn't be micromanaged. If you live very close to campus or work/life balance isn't something you're terribly concerned with, then you should be just fine.
