Microsoft

Great benefits.

Redmond campus has some great places to work.

Always a ton of interesting problems to solve.

Impact on computing, software development, and most anyone who uses a computer is hard to overstate.

Huge company, not even a company really, but a ton of smaller companies that don't always work well together.

Huge products like Windows, Office, etc., can stifle innovation that might lead to competition.

Many larger groups are run top-down, and giving feedback can be difficult, especially around arbitrary technical decisions.

Allow passion to thrive at Microsoft.

Help people build products they are proud of, not just working on, but using and having their friends and family use.

Engage the end-users and not just customers (customer being the computer manufacturer).

Focus on scenarios or workflows rather than features.
