Let me correct everyone’s misconceptions first. It’s not that you can’t enter a large factory with a college degree, but it’s just difficult. For example, Ali has many people with a college degree; it’s difficult to enter a large factory with a low education. You also need to have suitable referrals (connections) and just the right opportunities.
Of course, not all big companies are like Ali. Many big companies have academic qualifications that are mandatory indicators.
background
It is not a junior college of accounting, but I majored in mechanical automation at the beginning. It can be said that I came to the university for fun. I started to panic when I was about to graduate. After graduation, I couldn’t find a job. Under the guidance of my high school classmates (211 Jike), I became a programmer.
From the beginning of 4K to 14K three years later, it is no exaggeration to say that I was really drifting at that time, immersed in business, and lived a nine-to-five life every day. The salary is high and the work is easy, so happy!
The epidemic is coming
When the epidemic came, many companies closed down, and many programmers were forced to cut their salaries or resign. When I saw it, I really panicked. I asked my old classmates for study materials, interview notes, etc., for fear that I would lose my job if I was too late. !
Fortunately, the job was saved in the end, but the salary was reduced to 12K (it was said that the salary before the epidemic was over, but it was not restored until I left the job)!
idea of resignation
The idea of resigning is not because of other reasons, but mainly because I feel that the company is dying
A few months ago, the front-end colleagues of the company moved to our side, saying that it was for better communication (I believe he is a ghost), and later found out that the office area of the front-end colleagues had been rented out to others. . .
My salary has not recovered until now, I panicked a lot, and started the third study (preparing for job hopping)
Referral rejected
The first thing that comes to mind here is an old classmate, he is still in Huawei, and I want him to help push it in, the result is very touching
Although Huawei has no way to promote internally, he can help me internally promote Ali Didi and JD.com. These two companies do not require academic qualifications. The Java full-stack notes collected from ten years of development experience let me study hard;
After 2 months of hard work, I finally got out of customs with a high profile, and finally entered Ali on 5 sides;
note sharing
In fact, many people don't have a clear plan for themselves, and don't even know what route is suitable for them. In this case, you will be farther and farther away from the offer of the instrument! At any time, you need to have a clear understanding of yourself. Will you plan your learning route in advance?
The importance of learning the route:
You can review through a system to solve the problem of not knowing where to start and how to start?
Establish a systematic review system, each knowledge point is independent and related?
Review and summarize the interview points of the major factories, and start from your own reality to understand where the gap is?
Of course, in addition to these, there are also some beautiful learning materials, which are summarized very comprehensively, including 29 knowledge points, from basic to advanced!
