Many students CRUD every day, at a glance can see next year’s own. By March, you wanted to shake things up, so you scoured the Internet for interview questions, jotted them down, and went out to test the waters.

But it turns out that interviews are getting harder and harder. Do not ask the content of work at ordinary times, ask a lot of nouns are not heard of, what JUC ah, JVM ah, come up on a barrage, let you unprepared! Even suspect oneself is a fake programmer, feel what all don’t know!

Now, for example, projects of a certain size will use distribution. But under the distributed and will produce a lot of problems, just casually take the distributed call to say, if you use Dubbo, that must ask you Dubbo principle, communication protocol, SPI ideas, etc..

Dubbo is an XML file that uses the zK address. The zK address is an XML file that uses the zK address. If you think about it, 99% of the people meet the filter criteria based on how to use and configure XML, and it’s not your turn.

When asked about MQ, I have nothing to say except decoupling, limiting flow, and asynchronous. I can only “stare at each other with tears in my eyes”.

In fact, preparing for an interview is not difficult or time-consuming if done properly. If you don’t have a clue, consider the following brain map:
