Pros
Amazon is doing amazing things in so many areas: media, cloud, fulfillment, hardware, grocery, Fire/Kindle. The stock growth over time is great bonus too.
Kontras
Having multiple managers in a short period of time combined with moving between teams, resets the upward mobility opportunities. From 3 counts of personal experience (plus colleagues), management failed to take major life changing moments (i.e., birth or a death in the family) into account when allowing for time to celebrate or grieve. Meaning they didn't have a backup plan to cover for employee that was on a leave of absence. So instead of covering, they asked new parent or grieving employee to continue to perform at high level immediately following life changing experiences.
