Don't believe it, 98% of programmers are like this

The story

I went back to Beijing last week , It happened that my little brother didn't go to work , So I made an appointment to get together . After three rounds of wine , He suddenly showed a lost expression , I asked why , Just know that he is looking for a job recently , The process of the interview exhausted him both physically and mentally .

18 After graduation in , He went into a small company and engaged in java Development , It is almost three years now , In his words ： The company environment is good , But the salary doesn't rise . The business of the company is not very good , Leading to the gradual loss of personnel , He also wants to take the path of job hopping .

Do as you say , Take advantage of the holiday , He took a few days off , Interviewed several companies .

Very regret , One offer None of them received ！

The most annoying time , First of all, he spent more than an hour running to a company in Zhongguancun for an interview , As a result, we talked 10 Minutes less than , He was told to go back and wait for news . then , He spent more than an hour running home …… His heart , It's tenthousand ~ Gallop past ……

Speaking of this , He picked up the glass in his hand , Touched my , He said something reluctantly ：“ my dear friend , But how to fix .” Then one mouthful stuffs the wine in the cup .

Little brother, since you have asked me so , Let me be frank , Let's have an on-site interview , Do you think so ？ He has a smile on his face , Let me introduce myself first .

Little brother is also very cooperative , I said it right away ：

Hello, interviewer , My name is Peng .., Graduated from XX university , My major is computer information technology , from 2018 Has been engaged in java Development , I see your company is recruiting java Development Engineer , So I want to apply for this position .

Speaking of this, he paused , The feeling of wanting to talk and stop . Just as I looked at him , He said ：“ That's all for my self introduction ”. Have to say , I looked surprised , I even want to laugh ！ Just twoorthree sentences to introduce yourself ？ What's more, the content is the information you can see at a glance on your resume . Can't you say more , Too much short Is that right .

Forget it , Let me introduce myself first , A few more technical questions .

I immediately asked him ： Do you use Mybatis How long has it been ？ He answered three years .

I then asked ： Then you know why we created UserMapper.java Interface does not implement class , It can also be injected ？

His answer was indeed ：" Yeah , I didn't pay attention to this , It's usually used like this , No problem ".

ok , Nor is it a satisfactory answer , Let me change the subject ： Have you ever known about dynamic agents ？

This question , He did answer , It's all at the same time , The overall feeling is good .

therefore , Following this topic, I went on to ask ： Do you know about static proxy ？

He couldn't help laughing , Speaking of ：“ And static proxy ”？

ha-ha , I was also amused by him …… Then we talked about a few questions

Last , I came to the conclusion , He said to him ： As a friend , I know your code is OK ; But as an interviewer , I should also look at other candidates , Because when faced with such fundamental problems as why , You're not doing well .

this , Perhaps it is also a common fault of many programmers ：

Code of energy code in work , But I can't tell the implementation principle behind it during the interview ！

Many people may think this is typical “ Interview to build rocket , Screw in ”, Although there are so many questions in the interview , But it's still code when working .

I have interviewed hundreds of people , As a passer-by , I can responsibly say , This is not necessarily the case . During the interview , The interviewer doesn't know what your code level is , We can only examine you through some theoretical topics , About the problems in the project , At best, it is to ask some conventional practical questions . For example, what problems do you encounter online , How did it work out （ These can be prepared for the interview ）.

I have discussed with many interviewers before , Interview a person , Can you change the way , Such as writing code on site , But the cost is a little high , We have to improve the environment for him , There are too many interviewers, and the hardware is also a problem .

however , If you can't answer the basic theoretical questions , How to convince the interviewer of your actual code level ？

Especially when there are many people competing for the same position , The interviewer will compare more , From which to choose the best .

therefore , Interview is the first barrier before entry , We need to pay close attention to it . On the premise of sufficient time , We can strengthen our hard power , While improving soft power ,“ Two legs ” Walk ;

But many programmers are busy working overtime every day , I don't have much time to change jobs , Preparing for an interview . Now , If you want to get the offer, What's more “ Good steel is used on the blade ”！ Catch the most common 、 Review the core content , hit the mark ！

How to interview ？ How to interview accurately ？

Don't panic ！“ Everything has a law , Everything follows the rule ”, The same goes for interviews .

Before the interview 、 in 、 After that, there are strategies to talk about , There are routines to follow .

And these routines , I have summed it up in my knowledge planet （java Interview coaching ） in .
