Pluspunten
can't think of any pros in the company, if I can think of one thing may be salary of benefits, but it usually for the namesake and management will try to remove higher paid employees before huge vesting unless you are related to manager by background or willing to give good feedback to manager even if they are counterproductive to the company. I observed this more often with some managers who came from CapitalOne across Amazon.
Minpunten
Bad management, leadership principles are used against employees who try to do the right thing for company or career. Promotions are only given to employees whom management thinks will provide good review for their further promotion or related. You may not learn much here in terms of career development, technologies and tools are internal to Amazon, wont help a lot outside the company, other than AWS cloud. Management raises budget concerns during comp review, I have heard the same in many other teams in AWS, people are getting laid off or either will be removed by Pivot/PIP for any reason, whenever they reach higher vesting period unless their salaries are low.
