Pros
SMART People Amazon is truly dedicated to its customers Amazon is constantly striving to innovate There is a very flat structure at Amazon. Fewer layers and a real willingness on the part of even Sr. VPs to listen and engage means there is real opportunity to grow and make things happen. The scale of this store makes it unrivaled as a testing ground for ecommerce and user experiences. You can get enought traffic to test an idea at Amazon in one day that would take months on another site. Look, overall this is an amazing place to learn ecommerce at the highest levels, but they don't care about you or your life, and there is a trail of broken families behind many ex-employees. They'll give you the opportunity to work effectively on interesting stuff, then let you burn yourself on it and pay you less than you'd get elsewhere for doing less. Some thrive on it, others do not. I don't think anyone regrets their time here.
Cons
You will work every night and every weekend. This company has a very short memory. Last week's numbers are what matter. Because the structure is so flat and the VP pool still relatively young, there are limits to advancement in many job categories. The pay is not competitive They don't care about you.
