Ali's internal rank process
School recruits enter Alibaba, and the general rating is P5. A very small number of excellent school recruits can be rated as P6, and a very small number of Alistars can be rated as P7.
In Ali, ordinary employees can generally be promoted to P6 in two years, and half of them can be promoted to P7 in five years. It is very difficult to upgrade from P7 to P8. Because P8 is generally the leader of a large group, responsible for more important online projects, to achieve such ability and courage, it is not simply a matter of time accumulation.
P8 requires a team. It is generally difficult to have a ready-made team for you. Basically, you need to build a team with a few guns from scratch, and these few guns can reduce at least dozens of people, which is a big improvement compared to the original efficiency.
It can be seen that it is difficult to go from P7 to P8, and there are also many gaps between P8 and P9 that cannot be easily bridged.
Ali P8 notes
It has been 8 years since I joined Ali. The work pressure is high and the pace is fast. From the beginning of P6 to the current P8, I have indeed grown technically, especially when you maintain the system related to the big promotion. It took a lot of thought to do things without summarizing, so I compiled the work experience of the past few years into a complete note.
This note has helped many friends get offers from Tencent, Ali, Meituan, etc. And I bought it for 168 oceans, do you think it's worth it? (You taste, you taste carefully, you are welcome to post your thoughts in the comment area, someone should understand~)
Next, I will share the content of this document with you.

write at the end
A good architect is the result of the collaboration of opportunity (company), personal effort (hard work, willingness to study), and talent (true love). Only practice + opportunity + hard work can help you become an excellent architecture division.
Although I think that the research on technology is hard enough, but after reading this note, I know that I am a rookie. As a programmer, if I can't connect my technology from dots to lines, and from lines to planes, then I will die in this life. It is impossible to become an architect. If you want to double your salary, or want to touch the threshold of a million annual salary, then you may have to study this note carefully;
