Amazon.com – “Depends on what kind of manager you get...”

Pros

Challenging work - which means you learn a lot.
Somewhat of an open door policy, where you can talk to senior management.
High level of responsibility but equally rewarding financially and professionally.
Lots of smart people.

Cons

Too many meetings that sometimes seemed like a waste of time.
A lot of known issues that have not been fixed for long periods of time really surprised me.
Almost everyone is overworked, putting in over 40 hours a week. Probably closer to 50, and especially senior management.
Sometimes there was lack of direction, so you have to figure things out for yourself.

Advice to Senior Management

Focus on fixing known problems that drain more money than new projects bring in. I saw a lot of this and nobody seemed to care.
