Avantages
Amazon's Leadership Principals are the fundamentals of this company, and every employee is expected to follow. Frankly, that's the biggest thing I've learned in this company, in how to become a better leader by following these principals.
Inconvénients
Amazon's organizational leadership review (a.k.a. performance review / calibration) puts very heavy emphasis on keeping each of its employees on their toes. Calibration is not a new concept in many company - subconsciously, this happens even in the most caring of the companies. However, this company expects its employees to constantly deliver results and impact. The bottom x% will be managed out. This "bottom" is relative. If the org has everyone performing A+ and you happen to perform A- or B+, it'll be an uphill battle for you to stay in this company. Not to say that the goal post also constantly moves. There is no room to remain stagnant here, regardless of what people say here, and at what level you job is at. Furthermore, the company is also working to flatten out the organization to a certain degree. This makes growth in the company an uphill battle. Just as you've reached a certain point in career in your life, and a directive that sends you right back down to where you were at. Coupled with the company's recent decisions in making working here as unattractive as possible (e.g. mandatory return to office, reducing commute expenses eligibility, other perks) sends a chill down my spine that its ultimate goal, whether intentional or not, is to stealthily kick people out without cost and cause.
