Pros
Pay & inter-company mobility. Diversity of businesses. Cache of Amazon name. Lots of talented people gathered in one place. Opportunities to build your network, find mentors and be a mentor.
Cons
Experience is completely dependent on direct management. Know many who are very satisfied. Know more that are stress ridden, constantly under the gun and desperately unhappy but feel stuck because of the compensation. Consider the bonus hazard pay, especially if you are a woman. Very misogynistic workplace. Midlevel managers don't take this seriously. I found my job role unchallenging and monotonous. I know others at same level and job role feel the opposite. Lack of job parity across the org. My advice is to ask a thousand questions about the role you will be walking into and take promised changes with a grain of salt. Large turnover is disheartening and leads to constant team rebuilding. Leads to over reliance on individual performance and expectations to go above and beyond as a constant state of affairs. Teamwork and collaboration are undervalued.
