The junior college students were angry for 32 days, four rounds of interviews, five hours of soul torture, and won Ali's offer with tears

First correct everyone's misconceptions , College degree is not that you can't enter a big factory , It's just hard , For example, Ali has many people with college degrees ; It's hard to enter a big factory with a low education , It's not just the technology you need to be strong enough , You also need to have the right push people （ contacts ） And the right opportunity .

Of course , Not all big factories are like Ali , Many large factories' education is a hard indicator , Education is not good , It's no use pushing you inside ！

background

A non college diploma in family planning , Be a beginner majoring in mechanical automation . College can be said to be played , Approaching graduation, I began to panic , I haven't been able to find a job since graduation , Students in high school （211 Family planning ） Under the lead of , Programmers in the pit .

From the beginning 4K start , Until... Three years later 14K, It's no exaggeration to say , I was really floating , Immerse yourself in the business , Live a nine to five life every day . High pay , The work is easy , It's so beautiful ！

The epidemic is coming

The epidemic is coming , A lot of companies went out of business 、 Many programmers are forced to cut their salaries or resign , I was really flustered when I saw it , Find old classmates to learn materials 、 Interview notes, etc , I'm afraid I can't keep working late ！

Fortunately, the last job was saved , It's just that the salary has dropped to 12K（ It's the salary before the recovery after the epidemic , As a result, I didn't recover from my resignation ）！

The idea of leaving

The idea of leaving is not because of anything else , The main reason is that the company is dying

A few months ago , The front-end colleagues of the company moved to our side , It's for better communication （ I believe he's a ghost ）, Later, I found that the office area of my front-end colleagues was rented to others ...

My salary hasn't recovered yet , I'm in a panic , Started the third study （ Prepare for job hopping ）

Extrapolation is rejected

The first thought here is the old classmate , He is still in Huawei , I want him to help me push , The result is very touching

Although Huawei can't push it internally , But he can help me push Ali didi 、 JD.COM , These two families do not have a card degree , The premise is to improve the technology first , Then he threw me another one , The test notes compiled from their director's ten-year development experience , Let me study hard ;

I'm fighting hard 2 Months later, , Finally high-profile exit , In the end 4 Face into Ali ;

Only by constantly improving yourself , In order to stand out in the harsh environment

I am also a person who loves learning , I think learning is a long-term theme in the work of programmers . In order to help programmers change jobs and interview 、 A promotion and pay increase 、 Career dilemma , Improve your technology , This article gives you a complete set of quick learning methods and notes covering testing all technology stacks . So far, we have received feedback from seven or eight netizens , It is said that the interview asked a lot of knowledge points .

The content involves the ： Test theory 、Linux Basics 、MySQL Basics 、Web test 、 The interface test 、App test 、 Management tools 、Python Basics 、Selenium relevant 、 Performance testing 、LordRunner Correlation, etc
