Seeing such a post in the workplace forum, programmer A was laid off by the former company. After the layoffs, he was not particularly discouraged. He planned to start all over again, but was hit by reality.
When he graduated from college, he joined a well-known Internet company to work. During his work, he continued to study and improve his abilities. However, when he was 37 years old, he was laid off by the company.
He began to submit his resume to large Internet companies, but he refused because of his age. After looking for a job for four months, this was not an option. For the sake of his family and children, he began to compromise and submit resumes to small Internet companies. What I thought was that HR even disliked his ability to work. When he heard this sentence, he was probably out of anger!
Seeing what happened to this netizen, other netizens also started discussions.
Now employees over 35 are in danger! Because employees of this age are mostly labeled as moderate employees, stagnant motivation, lazy work attitude, etc.!
Even if you are excellent, your professional knowledge or technical level cannot keep up with the development speed of artificial intelligence!
Nowadays, both large and small companies value the comprehensive abilities of employees and not just their academic qualifications!
More important is your output value! Therefore, we can no longer pamper ourselves, we must always have a sense of crisis, maintain a lifelong learning attitude, and leave the comfort zone. It is really more choice than effort!
At the age of 37, he was considered old by those recruiting companies. I think those recruiting people take the elixir of life, do they stay young forever?
Think of yourself when you dislike others, unless you are the boss, otherwise everyone has that day.
I don't think that 37 is middle-aged, and the retirement policy is delayed according to future plans. At most, this age is young. Why do you always think that only young people are capable? Some things need to be accumulated and experience too. Losing these people is a loss.
On the other hand, if we study hard while working, we still accumulate more economic foundation.
Now it is also demanding to delay retirement. I'm afraid after thinking about it. When some companies see such older workers, they often have unfair treatment in terms of wages and benefits. Why does the country have no policy to stop this 35-year-old one-size-fits-all policy?
In the past, some people called jobs that were only suitable for young people to eat youth rice. Does the IT industry also eat youth rice? In fact, it is not. It's just that the IT industry has developed too fast over the years, and it feels a bit too late.
Way out
As a programmer, if you still don’t know anything in the face of new knowledge and new technology, and you still have a legacy of more than ten years ago, then you must be behind in knowledge and technology. If you fail to enter the management level, then you It will definitely be shot on the beach by the back waves of the Yangtze River.
Many programmers who are advancing with the times and good at learning are still the backbone of the industry. This just means that today's world has traveled all over the world with one trick, and the era of life-long eating has passed. A person must live and learn before he can walk in the world.
In my spare time at work, I will also turn over the interview questions of Dachang, so that I can always maintain the interview skills, and at the same time, I can understand the needs of Dachang for technology in order to prepare for emergencies, "Born in trouble, died in peace "The ancients don't deceive me.
Let me share with you a systematic growth and advancement route that I have summarized over the years of my own work, and share it for your reference.
Android advanced learning route
Learning route and information sharing:
I have been doing Android development by myself in the 5th year. In the second year after graduation, I was fortunate to join the big family of ByteDance. In the 4 years of Byte, I have witnessed too many people coming and going. I am deeply impressed by a colleague who switched jobs to Ali and directly doubled his salary. However, I also saw many people bumping into the wall with gold plated with "big factory". Technically!
I may be considered a successful example myself. I managed to achieve 2-2 from 1-1 in 4 years. Of course, the "sorrowful tears" behind this will be discussed later. In general, thanks to my continuous learning, review and summary, and improve my skills! Let me share my specific study route and notes in the past 4 years, hoping to help friends who are interested in improving technology!
