Pros: I like working at Google as an SRE (Site Reliability Engineer) because it is a job that combines my skills as a professional software engineer and self-taught system administrator. The work I do is quite varied, so I don't get bored doing the same thing over and over like I have done at other companies. Since Google is a well-established corporation, they can afford to provide some of the best benefits that other companies can't or don't provide. Unlike startups, you don't have to worry about the company going belly-up, nor do you have to work unreasonable hours. We have free food in the form of many cafes all over the area, each with a varied menu of foods. There's even a "concern" program that allows employees to call certain specialists for free advice. For example, you can ask a lawyer for some legal advice or talk to a therapist, amongst other services. The company even offers up to 3 months of paid medical leave. Aside from benefits, job security, and exciting projects, everyone there is very intelligent, and good peers/team-mates are essential in any corporation.

Cons: Large corporations have a certain bureaucracy and more red tape than startups, naturally. Promotions at Google require either someone to nominate you (which is rare) or self-nomination during regular performance review cycles. Performance review cycles are a big pain and a context interrupt. Many share this view, though it is believed to be a necessary evil.

Pros: Cutting-edge code ecosystem that is always improving. Great culture and people.

Cons: There is always a new tool to adopt because the old one is deprecated.

Pros: The line about working with systems at internet scale is absolutely true. You will work with more compute and network resources than anywhere else. Extremely talented and passionate colleagues.

Cons: Working on outside fun projects outside Google can be difficult due to the fact that the company's research interests are all over the map. This can cause things you do in your own time to potentially be subject to the company's copyright, even if you never relied upon resources from work to accomplish them.
