A new test came to the company. He looked like a kid, but he didn't expect it to be a new generation of roll king. . .

Inward scrolling is a very popular word now. As the popularity continues to rise, it has faintly reached the level of "everything can be scrolled".

In the programmer workplace, what kind of person is the most disgusting?

Is it someone who is not good at technology? Not really. Colleagues with poor skills, we can help him.

Is it someone who is too technical? Not really. 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 with mediocre skills but eager to express themselves, work overtime until 12 o'clock every day, and behave extra positively in front of the boss, making other people very embarrassed. This is the "roll king" in the industry.

​

Last month, many new faces came to the company, and one of them was born in 2000. Although it brought some new blood to the company, it also made me realize that I am indeed not young. This little brother graduated last year and has worked in a software company for half a year. Now he has switched to our company with a starting salary of 18K, which is almost close to mine. It was only later that I found out that he used to be a paper king, and he never left his studies on the way home from work, and he never even left his mobile phone on the way.

In the past two days during the company team building, he drank too much and chatted more openly. Only then did he realize that this little brother's family conditions are not very good, and his parents have no pension, so he lives on him. So he started self-study for the test in his sophomore year, and got an internship opportunity in a small company in his senior year. Continuous learning and practice at work took twice as much time as others, so I was able to lay a solid foundation, and now I can work with ease.

​

I think this little brother is a role model for us to learn from. It's not that we should learn from his overtime work and introspection, but his spirit of continuous learning and advancement!

Only by constantly improving yourself can you stand out in the harsh environment of involution

I am also a person who loves to learn. I think learning is a long-term theme in the work of programmers. In order to help programmer friends change jobs for interviews, get promoted and raise their salaries, face career difficulties, 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 foundation, MySQL foundation, Web testing, interface testing, App testing, management tools, Python foundation, Selenium related, performance testing, LordRunner related, etc.

The above knowledge point documents have a total of 117 selected pages. They are suitable for those who want to increase their salary, change jobs, or need to improve their technical capabilities. It is definitely not realistic to show all of them for everyone. In order not to affect your reading experience, only part of the content is shown.

Finally, I would like to give you a word: the earliest time to plant a tree was ten years ago, and the second is now. Only by working hard now can miracles appear to you, and if you stop, you will only be eliminated!
