I interviewed a 33 year old Android programmer, who could only program for Baidu, but wanted 25K, which was met by me

Want to make APP Same thing as WeChat , Can run small programs smoothly ？ | Experience will send you to Xinjiang 、 Huawei 、 Cherry keyboard ！>>>

Recently, I saw such a post in the forum ：

Interviewed a job 12 Programmer of ,

This old brother has 3 year java Development experience ,2 year H5,7 year Android Development experience , It says proficient Java,Android, be familiar with H5 Development . There is no specific technical point .

To be honest, I'm looking forward to the interview of this old brother , So he was invited by the personnel .

My brother's interview is very impressive , I respect him, too , After a wave of self introductions , We got to the point .

I asked him Jetpack, He said almost never used Jetpack, So I gave him a little example , The answer that elder brother gives me is Baidu can solve .

So I asked him again Groovy, I still don't know , So I asked the most basic Handler,Binder Wait for a few key words , It's still not clear , Old brother is still so strong and aggressive , The feeling he gave me was “ Do everything , You don't ask these useless ”.

Look at his resume. It says , Proficient in Android Development , Familiar with cross platform development ,js Interaction , I asked to understand Flutter Do you ？ He said he didn't know that he had never heard of , Finally, he asked about the expected salary, and he said 25k, I don't know what to ask , So the interview ended in a hurry .

After reading this post, I thought for a long time , It's not easy to understand . Where should we go for older programmers , In particular, no management experience will only Baidu copy paste programmers how to make a living ？

Today's technology environment is not like it used to be , In the past, I couldn't find any information on the Internet , Can't , You have to find the document yourself （ A lot of them are in English ）, Look at... One by one , Try it one by one , And find a way to solve the problem . It's not the same now , This is the era of information explosion , The problems you have encountered have been encountered by others for a long time , And then share it online , So don't worry about not finding the answer , Because you're not the first to eat crabs . Just look for , I'm sure we can find .

Of course, if you have been using search engine oriented programming ideas to develop , I believe that you will soon reach the bottleneck of knowledge , And then it's repeated accumulation , Physical work , It's what we call Manon .

So how to avoid the above problems ？ Here are some suggestions ：

• When you encounter problems, you should first come up with a set of solutions through your own ideas , And then implement it . idea 、 The idea is crucial , Search engine is just one of the tools to implement it .

• To have some familiar technical knowledge website , such as github、stackoverflow、segmentfault wait , Suggest that you can find answers directly on these websites, which will be more efficient .

• Always sum up your knowledge , Have a set of their own knowledge system , Learn to grow systematically .

• Have the ability to learn actively , Through the study , We can slowly shape critical thinking 、 Creativity, etc . No one can teach these abilities , It's up to us .

Now I'd like to share with you a systematic and advanced route of growth that I've worked for several years , To give you a reference .

What are the ways to learn ？

mention “ Study ” This word may give people some uncomfortable feeling , It always reminds people of the years when they were young and buried in the dust of blackboard , Or join the company's boring organization “ The photocopier ” Low quality education activities like training . Here are some ways to learn ：

• Form a circle ： It is suggested to set up a small learning circle , There will be a higher quality of learning ; We can also share and exchange knowledge ;

• read ： A year 30 Ben's reading goal , Let's make it happen . For reading , We can divide it into intensive reading 、 Read through two types ; The best accuracy of books with professional skills . In addition, we recommend you to read books written by foreign experts Daniel , Because the quality of domestic books is really average , It's basically for junior programmers .

• Replace learning with teaching ： Explain to people outside the field ; Learn to be a preacher , Be a person who is willing to share actively ; You may have heard the story of the rubber duck , It describes the explanation through self talk , It has solved the problem that has been puzzling for a long time .

• The story of the rubber duck ： You are solving a difficult problem , A lot of time has been spent , The deadline is imminent . At this time , You asked a colleague for help . They come to your screen , You start explaining what's going on , What went wrong . Not much has been said , There's a flash of light in your brain ,“ ah ！” I cried , You found bug. A confused colleague has not said a word , He shook his head and left .

• Talk to the Cowman ： I've seen too much , Sitting in the office for a day TX; Move it , In the thought collision with the master , It's easier to be inspired . I'd like to recommend some ways to get to know Niu Ren ： Big show , There are usually a lot of Tauren ; Various wechat groups 、InfoQ There's a lot of big players on it ; I became a hero through technical creation , Naturally, it has increased the channels to know more cattle people .

Career promotion is not as difficult as you think

Why talk about this topic , Isn't it good to stay in the comfort zone , Do what you are good at every day .

Because every step of our programmer's promotion , We need to do a lot of things we haven't done before , Things that haven't been dealt with , We need to be in the way we do things 、 Ideas 、 Make big changes in your habits .

But capitalists are cold-blooded , If you've been in the comfort zone , When you're not as skilled as people , He was kicked away with one kick , So be prepared , Save against a rainy day , Promotion is not for the company , But for yourself .

Recently, I collected an internal document compiled by the great God Ali , contain 【Android Developing core knowledge notes + Architecture video +2020 The latest interview of big factory + Source notes 】. If you are stuck in the bottleneck of lack of learning resources , So it's just right. I can help you .

Finally, I'd like to send you a message ： Action is Laozi 、 Knowledge is a son 、 Creation is grandson . I hope you can find your own way , To achieve a continuous breakthrough in life .
