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/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 -- e.g. 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 (rare) or self-nomination during regular performance review cycles. Performance review cycles are a big pain and context interrupt. Many share this view though it is believed to be a necessary evil.
