Many students CRUD every day, one can see myself next year. March, when you wanted to change the status quo, I looked for a large number of interview questions online, then forced to write down, start out "test the water."
But I found that interview now, how more and more difficult. The usual content of the work do not ask, ask many of which were never heard of the term, what JUC ah, JVM ah, come on meal chain gun, let you surprise! Even suspect that he is a fake programmer, did not know what it feels like!
For example, now a little-scale projects, will be used distributed. But will generate a lot of problems in distributed, it simply takes for distributed call it, if you are using a Dubbo, it is certainly going to ask you to Dubbo principle, communication protocols, SPI thinking and so on.
But a lot of students, usually only know how to use, ask the interviewer to Dubbo, Dubbo are the first to explain what the term is, and then tell you how Dubbo is used, such as how to configure XML file zk address and so on. You want to know what, if in accordance with how to use XML to configure how how to do this filtering criteria, that an estimated 99 percent to meet people, that's not your ah. Java Architecture Community
Asked MQ, in addition to decoupling, current limiting, asynchronous addition to these six words, it basically in nothing to say, only the interviewer and "doubted see tears in their eyes, not even know what to say."
In fact, if done correctly, it is not difficult to prepare for the interview, do not waste too much time. If you have no idea, the brain can refer to the following diagram:
