Involution is a very popular word now. As the popularity continues to rise, it has gradually reached the level of "everything can be rolled".
In the programmer workplace, what kind of people are the most disgusting?
Is it someone with bad technology? Not really. Colleagues with poor skills, we can help him.
Is it someone who is too technical? Nope. Colleagues with strong skills are hard to come by, and it is too late to learn from him.
What is really disgusting is that people who are mediocre in technology but eager to express themselves. They work overtime until 12 o'clock every day, and they are extremely positive in front of their bosses, making everyone else embarrassed. This is the "roll king" in the industry.
The year of 2022 started, and many new faces came to the company last month, and one of them was from 2000. Although it also brought some new blood to the company, it also made me realize that my grade is indeed not young. This little brother graduated last year. He worked in a software company for half a year, and now he has moved to our company with a starting salary of 18K, which is almost close to me. Later, I learned that he used to be a master of the book, and he never left his studies on the way to get off work, and he never even left his mobile phone on the way.
In the past two days, he drank a lot during the company's team building and chatted more openly. Only then did he realize that this little brother's family conditions were not very good, his parents didn't have pensions, and he was living on him. So he started self-study tests when he was a sophomore, and got an internship opportunity in a small company in his senior year. Continuous learning and practice at work, spending twice as much time as others, so I can lay a solid foundation, and now my work is also handy.
The Programmer's Day just passed some time ago, and the significance of the 1024 Programmer's Day is to pay tribute to those programmers who pursue knowledge, technology and innovation.
I think this little brother is an example for us to learn, not that we should learn from his overtime work, but his spirit of continuous learning and advancement!
Only by constantly improving ourselves can we stand out in the harsh involution environment
I am also a person who loves to learn, and I think learning is a constant theme in the work of programmers. In order to help programmer friends jump job interviews, get promotions and raise wages, career dilemmas, and improve their skills, this article provides you with a set of quick learning methods and notes covering testing all technology stacks. At present, I have received feedback from seven or eight netizens, saying that the interview asked a lot of knowledge points.
The content involves: testing theory, Linux basics, MySQL basics, Web testing, interface testing, App testing, management tools, Python basics, Selenium related, performance testing, LordRunner related, etc.
