Pros
1. You will get experience from the top cloud computing company out there, it's months ahead of the competition (Microsoft are catching up) 2. Most customer centric company I've ever worked for 3. You will learn where technology is headed for the next 10+ years 4. This job will set you up for your next job - Most sales people leave after 18-24 months, many employees actually call it a "Cloud MBA" since it will open up many opportunities after your initial 12 months there. 5. Getting a meeting with new customers is a lot easier than any other company I've worked for (people really do love the Amazon brand)
Cons
1. Very poor compensation and benefits (Most employees I've talked to took a pay cut to join AWS) 2. Least employee centric company I've worked for (employees are treated as a commodity) 3. Reaching your sales quota has to do a lot more with luck and there is no real science that goes into calculating it 4. You won't get any "real" professional development training 5. Be prepared to be heavily micro managed 6. Highly immature and condescending management team 7. You will spend more time attending territory reviews, building account plans and will be attending internal meetings, rather than meeting with customers.
