Pros
1. One of if the largest employer in Silicon Valley. 2. Great healthcare and childcare benefits. 3. Very large company with many orgs and many teams. You have opportunities to transfer internally to another org if you don't like the teams and politics in your current org. 4. If you are a new college graduate, there are many opportunities to join and the senior people tend to be helpful to those who are new and young in their careers. 5. Many people spend their entire careers here. Lots of employees with 20 and 30+ years at the company.
Cons
1. Some roles are very specific to the company, in terms of title and job duties, and may be difficult to transfer to other companies in the future. 2. Like many large companies, there are politics and favoritism. And all orgs will have some bad managers and leadership. But the company is so big, that one persons experience in one team can be completely different from another persons experience in another team. 4. The bad teams will have noticeable turnover, avoid them. 3. Many roles demand high working hours with management pushing escalations and urgent tasks, comparable to other top tech companies. However, the salaries here are much less than them.
