Avantages
You can learn how to lead a team and be good with handling completely chaotic situations. The people you work with will become family. Even if short lived.
Inconvénients
Amazon has gone back to their old standards of hiring and promoting but worse. You can't be hired as a supervisor of the street except in very rare circumstances. Never once at my building. keeping it internal and hoping employees work less than 1-2 years max. Thier strategy was to have always fresh new ideas. Instead of internal though you can only promote out of your building with this new program. It causes problems either way because the associates don't have consistent leaders. One day you walk in and have a new manager who has to fumble through the job without proper training.
