The inner volume can be said to be 2021 The hottest word in .2022 The year has just begun ,LZ I see a lot on many programmer websites Java Programmer's 2021 Annual summaries are :Java
It's getting more and more curly ( Manual dog head ),2021
Year is the year of being rolled up . Millions of graduates are eyeing , Later, on-the-job personnel took the lead “ loaf on a job ” Occupying the pit , Coupled with the epidemic, many companies have closed down , There are not so many jobs on the market . come very naturally HR
We began to choose the best from the best , Planned volume contradiction !

So how to stand out among many candidates ?

One of the answers is to find out the interview routines of Internet companies ! Let's take big factories as an example , Their interview questions all look like this :

* Let's talk about a collection framework and a whole framework
* Why? hashmap To be in 8 Tree when
* What design patterns do you know , They are JDK How is it reflected in
* What scenarios are the thread pool rejection policies used in
* G1 Two region Not continuous , And there are reachable references between them , I'm going to recycle one of them now , What about the other one
* know of CMS Concurrent preprocessing and concurrent interruptible preprocessing
* ......
how , Does it feel different from what everyone asks in the interview , No, what is it Java Object oriented , What? Talk about it Spring I understand ( Manual dog head )

On the other hand, it is necessary to know what skills need to be mastered for different job levels ( If you are interested , Little assistant at the end of the text , You can get the corresponding Java
Learning route , Zero foundation and architect's LZ Both )

The third one is to dig deep into the current high-frequency interview questions , Don't mention cramming before the interview , Take a high-frequency interview manual system to find out and fill the gaps. How much is helpful to you ! What a coincidence , this LZ
