Pros
Smart people. Brand recognition when you tell people where you work. Being a part of history. Good salary, (but read below, as the money is definitely not worth what the company asks of you).
Cons
The growth of this company in the Fulfillment world is so fast, that the tools can't keep up. The excel files. The models. The homegrown systems. They are absolutely horrendous. It will take you 60 hours/week to do what it took you 40 hours/week to do in your past life. No matter how fast and efficient and smart you are, it will suck the life out of you. During peak season (Late Oct-Dec), you will work 80 hours/week minimum. Additionally, training is non-existent. You are literally dropped in to a building and left alone. While courageous people can do this in some settings, it's completely crippling in a company with 250,000 employees. There's no one to help you connect to the bazillion servers you need. No one to help you with errors in file. No one to explain the sea of reports and files you're expected to complete. You are literally completely alone. This is why attrition in the management levels of the Fulfillment Centers is so high. Few people last a full year. There's a running joke that you're an "old timer" if you've made it past 8 months. I used to read Glass Door reviews and think this was just a bunch of negative people airing bad blood. Unfortunately, it's people providing real perspective of what the company is like on the inside. I wish I would have listened to the reviews and that I wouldn't have taken this job.
