This is the first day of my participation in Gwen Challenge

preface

June 20 years average 2 graduation, graduation and my girlfriend’s idea is to find a second – and third-tier cities with a normal salary with the help of their parents to buy a house to buy a car and then live a happy life, because I’m yearning for life so even if my classmates went to Beijing with my internship and I don’t have any wavering, to the south with his girlfriend chose huizhou; But the experience of less than a year has left me… There is a big gap between my ideal life and reality, and I always feel less passion for struggle, and I am afraid of losing my competitiveness. The most important thing is that maybe my parents can help me with the down payment, but my monthly payment is not enough. Fortunately, UNDER this anxiety, I have been improving myself. In addition, my friend’s job-hopping salary stimulated me, and my girlfriend’s encouragement and support made me free from worries, so I had the interview experience and the interview for one and a half months.

I will write a branch to write the following questions, because more I will not post the answer, and the interview questions are relatively simple, I hope to help you to consolidate knowledge points aftertaste; This is the first article I sent out in the nuggets, I hope you can help me put forward suggestions ~

A State-owned enterprise in Beijing

The Beijing one was recommended by my friend, because the treatment was very good, haha, but later because my girlfriend could not adapt to the northern climate and did not go to Beijing, I gave up the second one;

1. New features of VUe3.0
2. Responsivity principle in VUE
3. Es6 usage
4. Promise the commonly used API
5. How to make the browser not cache

drops

Didi made two group interviews for four times. I am very grateful to Didi for helping me find out many shortcomings. A good summary will be of great help to my subsequent interviews.

1. Introduce the project
2. One scenario :(because I talked about the interface that calls data frequently but hardly changes, cached in localStorage during login) what about the interface data that you cache during login if the data on the back end is wrong?

Write in the last

The one-and-a-half month on-the-job job hunting experience has greatly improved myself, not only in terms of skills, but also in terms of mental endurance. Thank each to the interviewer to give my an interview, I realized my own shortcomings, I usually way to learn is technology blog and geek time, build the knowledge system of some messy, mostly some points, haven’t connect line and figure, should pay attention to the computer network, operating system, the computer basic data structure algorithms, and front end, Mastering these things enables you to adapt to changing front-end technology. ‘!!!! Next, I plan to build a knowledge system through books. My short-term goal is to brush up JS Little Red Book and learn React in depth

Don’t be discouraged if you are still trying to interview me. During the one and a half months when I was looking for a job, my business was not only busy, but the company also forced me to work overtime. I communicated with hundreds of companies on Boss, and I submitted at least 30 resumes through internal promotion. Finally, I met with 10 companies, and about 3 of them got offers. I don’t remember how many times I wanted to give up during this period. I met a lot of strict interviewers, gentle interviewers, some people give me encouragement, but also some people face helpless ~ even one side of the interviewer evaluation of my foundation is good, the second side of the interviewer evaluation of my foundation is too poor; Here is my favorite sentence: there is no useless experience in life. As long as you keep moving forward, the sky will always be bright. I believe that the nuggets friends are better than me, I have persevered, you will get better results than me, must not be discouraged
