In short, it is an extraordinary year. Now that you are not ordinary, you have to do things, and then choose to find a job decisively, and by the way, get lucky in an extraordinary year.

Introduction

Mengsheng's decision to resign and change jobs also followed the situation and feelings, because there were already signs of not being able to stay before the 2022 Spring Festival holiday. After enduring the 2022 Lunar New Year, the substantive decision was made directly after the completion of the Spring Festival holiday. The resignation operation, the full-time work in February, the year-end bonus, all of which are not needed, if you say go, we will go, and you will be in Kyushu. Here I want to say that I am facing a front-end development position.

main topic

The above said so much is a foreshadowing for the interview and job search for my own job change in 2022. I arrived in Shanghai on the last weekend of February 2022. I remember that I arrived in Shanghai on the evening of February 25, and then In the afternoon of the same day, the phone interview had already begun, and it had laid the groundwork for the first day of the actual interview. The first day of the job interview is February 28th, so let me share what I saw, heard, thought and felt on the first day of the actual interview.

I remember very clearly that on February 28, the weather was sunny and the sun was shining brightly, which seemed to make people forget that it was still early spring, and the clothes I wore were still thick jackets, but to be honest, the weather in Shanghai was similar to the temperature in my hometown. , still frozen into a dog, but fortunately I was wearing a jacket instead of short sleeves. The first offline interview on the first day of the interview was the re-examination. I set the alarm clock at 7:00 and got on the subway at 7:30. Then I took the wrong direction and almost didn't arrive at the agreed interview time. The interview location, but after arriving at the interview point, I feel much better after seeing the interviewer. The interviewer is the person in charge. When I look at his sparse hair, I know that he is a technical boss, and he is a very good person. The tone of asking questions He was also very kind, and he didn't ask too many technical questions, mainly about practical application scenarios. I recalled the interview questions at that time, and summarized:

 1、原生开发和h5交互的时候，是通过什么方式来实现的；
2、在填写表单的时候，进行空值判断的时候，如果表单填写选项很多的时候，怎么做空值校验；
3、是否使用过uni-app，小程序开发的项目；
4、混合开发flutter技术的使用情况；
5、前端开发的时候使用框架的相关内容。

Then I talked about some company projects, and I didn’t ask many questions. After arriving in Shanghai, I received the first round of phone interviews with the company. The phone interviews were successfully passed, and then the offline interviews were arranged. I arrived in Shanghai for the first time. I didn’t adapt to the rhythm of the city, and I wasn’t familiar with the humanistic habits, so I thought there was no drama, and it was precisely because there were not too many interviews and conversations this time, which laid a great foreshadowing for the later work. I will say at the end that this time The final result of the interview.

After the interview at 11:00 in the morning, I have been answering the phone, either for an interview or for an interview appointment. It can be said that I am either answering the phone, or I am on the subway where the phone is answered. I am very busy and feel very fulfilled. Before I knew it, the interview session in the afternoon was mainly based on remote interviews, video interviews and telephone interviews. There should be about 6 interviews, which lasted until about 8 pm. Most of them were the first round of remote interviews. There are too many front-end questions, but they are all common knowledge points of front-end development. According to the memory and the records at that time, the interview questions asked by the interviewer are summarized:

 1、v-show和v-if的区别，以及适用的使用场景；
2、描述一下Vue的生命周期，父子组件谁先加载谁后加载；
3、组件之间通信，传值的方式；
4、网络请求中接口报404错误是什么原因；
5、http和https的区别，为什么要用https；
6、谈一下webpack的使用，以及原理；
7、怎么实现class的垂直居中；
8、讲述闭包，以及使用场景；
9、浅谈vuex的原理；
10、介绍一下promise的使用；
11、Vue双向绑定原理；
12、数组去重的方式有哪些；
13、如何理解前端模块化；
14、讲讲JS的原型链；
15、你平时用到的web前端的性能优化有哪些；
……

With my superb memory, I have recalled so many interview questions. I forgot the others, but they are not too bad. Generally, the questions asked in the first round of remote interviews are not difficult and very basic, and they are mainly commonly used in work. Knowledge points, as well as the basic knowledge points of front-end development, so the front-end development partners must prepare the basic knowledge of the front-end before looking for a job. It is not easy to remember all of them, but they must be prepared in advance, so that You will get unexpected opportunities.

Because there are too many companies that invite interviews, the pace of interviews in the next three days is more intense and time is not enough, but I still follow the arrangement of one offline interview in the morning and one offline interview in the afternoon, with various remote interviews interspersed in the middle. And the phone to communicate with HR for interview. My principle is that offline interviews generally limit the distance to within one hour of taking the subway. I don’t consider companies that are farther away, because it is impossible for me to move when my job is uncertain. I forgot to mention, I am boarding at a classmate's house, and I suggest you not to move blindly when the job is not confirmed or if you have not changed into a regular. The risk is very high.

Speaking of which, the time has come to nine o'clock in the evening on the first day of the interview. After eating and washing up, I will sort out the interview information for the second day and check the relevant offline interview route and travel time, so that I will make a decision on what time in the morning. Get up and set the alarm clock. By the way, review the knowledge points of the front-end interview, check for omissions and fill in the gaps, and strive to make yourself answer more perfect during the interview, and get more opportunities for extra points. In short, the time other than the interview is to review the knowledge points, and also to summarize all the knowledge points that were asked during the interview that day, including the knowledge points that I answered poorly or did not answer, it is best to make a record, and then by the way Check the corresponding knowledge points, so that you will not "roll over" when you encounter the same question in the next interview.

Epilogue

The first day of the interview like a war ended like this. I didn't get an offer for the time being, but two interviews entered the re-examination stage. Finally, to sum up the day: although tired, but very fulfilling; although not fully prepared, but feeling good. The preparation of knowledge before the interview is very important. Welcome to pay attention to the WeChat public account of the three shopkeepers "Program Ape by the three shopkeepers" for communication. Since I didn't prepare and sort out much when I first started the interview, it led me to the second day of the interview. The embarrassing situation, the next article will share in detail.
