Ali P12 is a senior chief researcher. Most Alibaba P12s do not focus on current productivity, they only do things that set rules. In terms of productivity, if P11 is the commander in technology, then P12 is an army. Alibaba has two job level systems, one is the P sequence, representing technology; the other is the M sequence, representing management.

P and M have a corresponding relationship. P3 and below, low-end functional positions and outsourcing, there were campus recruitments of P3 in the early years, but now there are no more. P4=specialist, fresh undergraduate, no corresponding management position, there are very few P4s at present, Alibaba campus recruitment basically starts from P5, as long as the level is high.

P5=senior, fresh graduate, high-level fresh undergraduate. Social recruitment with high potential starting point (Ali social recruitment generally requires 2 years of work experience and starts at P6. Occasionally, some people with high potential but low work experience will be hired and given a P5. Social recruitment P5 will often be promoted to P6 quickly). There is no corresponding management position.
