Foreword

Remember a quote from Forrest Gump "Life is like a box of chocolates, you never know what the next one will taste like"

So there are many explanations for layoffs, in our case it is called Indulgence~

The collective indulgence began in June; The initial rumors were heard on the pulse, and after the fight between our two bosses was over, I was also affected, and the winning boss kept himselfPeople, we are merged to like Indulgence List

After experiencing a series of activities such as unwillingness, hard work, and lying down; I am also ready to accept n+1 and leave the place of my first job; however, I was informed that I was left,Maybe I'm too cheap, maybe the list is enough, maybe the new leader is fighting for it

I thought the end was the beginning. In the following time, everyone started to involute. The project in charge was taken over by a school recruiting students, and the team atmosphere was poor; It turned out to be me taking the initiative to indulge

This more than one month experience has brought me from fairy tale to reality, and I have grown a lot.The road to the future is very difficult, I will never back down, I will face it bravely, today's efforts are only for the future!

There is no shortcut to learning.We should pay attention to memorizing learning, not only memorizing, but also writing down our experience, writing notes, drawing pictures, summarizing, etc. There are many ways, but we must do it carefully and don’t believe it too muchOne's own memory, only repeated memory, deepen understanding Caixing.

At the same time, for programmers, it is not just rote memorization, we have better ways to learn, such as writing demos to verify.When reviewing the knowledge points, you should combine them with the projects you have done in time, so that you know how to talk during the interview, from the project to the knowledge points, and from one knowledge point to another knowledge point.After reviewing to a certain stage, you can try to connect these things in series, from point to face to form a knowledge system.

I believe that as long as you are fully prepared, you can get a satisfactory offer and embark on a new level of life!If the article is helpful to you, please like and collect it, or share it with your friends, thank you for your support!
