Pros: Engaging, challenging, friendly, fun, top.

Cons: Fast-paced, competitive, and changing. Fast. Fast.

Pros: Google is very widespread and offers interesting problems in many areas. Google has great pay and excellent benefits.

Cons: As a big company, Google has lots of politics. It has become hierarchical and there is lots of overhead, like meetings. The 20% time is touted, but not that real in practice.

Pros: Smart peers; decent problems to solve; loads to learn; decent compensation; good perks.

Cons: Though there are tons of good problems to solve in good projects, the good work is reserved for L5+ engineers, as they need complex work to get promoted. Managers assign responsibilities based on what is required to ensure people get promoted to the next level, and not because they are interested in solving the problem or they have the ability to solve the problem. You have to make your manager happy to get good work; the promotion process is totally crap. People do the wrong things to get promoted. People don't do the right thing because it won't help with promotion. Some people become people managers just to grow and not because they are interested in managing people.
