As a junior college student, I studied hard in closed doors for 56 days, won Ali offer with tears, five rounds of interviews and six hours of soul torture

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 just 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 ！ The background is not a college degree 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 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 ） Internal push was 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 , They are a collection of ten years of development experience  Java  The whole stack of notes , Let me study hard ; I'm fighting hard  2  Months later, , Finally high-profile exit , In the end  5  Face into Ali ; In fact, many people share notes , There is no clear plan for itself , I don't even know what route is suitable for , In this case , You'll be out of your mind  offer  More and more far away ！ No matter when , We all need to have a clear understanding of ourselves , Will you plan your study route ahead of time ？
