How are the ranks of Alibaba employees divided?

In the early stage of development, Alibaba was classified according to the functions of "management" and "academic". The levels of management functions are: responsible person, manager, director, VP, senior VP and CEO；; The levels of academic functions are: warrior, knight, hero, master and chief; ; Each level is divided into three levels. Later, Alibaba changed the classification form of ranks to two simpler functions: M (management) and P (specialty), and each function was divided into eight ranks of 1-8. After that, M is subdivided into ten ranks of 1- 10, and P into fourteen ranks of 1- 14.
