Pros
Generous (though somewhat volatile) compensation. When the stock is not doing well, the pay is just okay. When the stock is doing well, it can be quite lucrative, especially if you hang around long enough to ride the waves.
Cons
There are some great people at Amazon, but there are some toxic people (and teams) as well. Find a good department and team and Amazon can be great. Find a bad one, and life can be hell. Transfer if you can ASAP. The biggest problem are the way global policies are announced and carried out without feedback heard from employees. The way the layoffs were handled (with a looming threat for months), and then the way the remote work policy was rolled out then rolled back was truly one of the most abysmal showings in corporate history.
