A few days ago, I received a private message from a fan, saying that he only had a year and a half of experience, but he was asked various questions about distributed, high concurrency, and multi-threading when he went to an interview. On the basic level, you can answer it, but if the interviewer asks in depth, you can't! When I was asked, I wondered whether the Java recruitment for junior positions is junior development or architecture. Can I directly enter the architecture team after interviewing? (manual dog head)
But in fact, there is one thing to say , most programmers have experienced the situation of building rockets during interviews and screwing screws at work . The interviewer asks this just to judge your learning ability and technical sensitivity; at the same time, through this, the interviewer can immediately know whether the candidate has been learning and pursuing the depth of technology in private. It may be a bit difficult for friends with one and a half years of experience to directly get in touch with these things. If you learn these things by yourself, you can't figure it out at all, and you don't know what problems will happen without actual projects! But these are indeed what the current market needs. If you don’t master them, you will lose the so-called core competitiveness.
Therefore, in order to help you better learn core technologies such as distributed, high concurrency, and multi-threading, LZ today brings you a high-reputation report from major Internet companies such as Ali, JD.com, and AutoNavi, as well as many experts.
