Pros
The Leadership Principals are not just words. They are the culture at Amazon. Fluid environment is the perfect landing spot for the self-driven, growth-minded person looking for a dynamic, flexible environment to add value and do meaningful work. The benefits and compensation are generous and the growth potential is extremely high. There are many resources, collaboration opportunites and flexible boundaries to solve problems creatively. Things move and change at a very fast pace so boredom is not an issue. The company invests in new employees by allowing them a generous 3 months to train, learn and adjust before being put into active duty. Virtual work with an option to go into the office at will. IDE , Sustainbility, and Mental Health & Wellbeing are all huge here.
Cons
So far, there aren't many cons. Because things move so quickly, some internal systems are not yet created. Rapid change can cause mis-alignment and confusion at times, but not insurmountable. Fluid environment would not be the right place for someone looking for a highly structured, rule-minded role.
