Pros
I got hired right out of college. I would recommend any college graduate to start their career with Amazon because it will teach you the work ethic you need to survive in the real world. This work ethic will carry with you for the rest of your life and anything you do after Amazon will be very easy to you. You will work with very smart young leaders. My GM was not even 30 and he had moved every couple years for a promotion opportunity. There is a lot of growth if you are willing to come in everyday and work hard. Work week in the Operations department is 4 days but I would say that I only worked 4 days 50% of the time I was at Amazon. During Peak, prime you are working 5 days. In my building a lot of managers were leaving; either getting promoted or quitting the company so most work week were 5-6 days 12 hours. Amazon also gives you a lot of flexibility on how to manage your people. You get about 200 associates to manage and you can really set those relationships early on so that your shift can produce. Overall I had a good experience working for amazon. I left because I found a better opportunity else where in terms of work/life balance.
Cons
Work/Life balance - Average work weeks are 50-60 hours and weekends are the busiest as it is with any retail sector. Culture - Everyone is a number to them. From your associates to managers. Turnover is so high that anyone can be replaced. After one year in my building I was the oldest manager. Intense Work - You are constantly on your feet while you are at work. Majority of the times I wouldn't even have time to eat lunch. Your Ops Mgr's wouldn't remind you to take lunch because they couldn't afford to lose you off the floor for even 5 minutes. Leadership - Your site lead / GM changes every 6 months so everything that you have been working goes to trash once the new GM comes. Usually the GM doesn't know what they are doing so you go through a rough patch whenever their is change in leadership. Promotions - If your building is doing bad as far as productivity goes you will never get promoted. It took me over two years to get promoted from Mgr I to Mgr II even though my peers which weren't good as me got promoted earlier in their careers because their building was doing good.
