I have had some interviews recently. After the end, I found that there are many shortages of knowledge and insufficient attention to thinking. The brief summary is as follows
First of all, in terms of basic knowledge, the basic principles need to be further solidified. The exploration of the underlying principles should be accompanied by any technology. If the foundation is not solid, the ground will shake. It is also necessary to systematically study java, including any technical details, and the study plan needs to be arranged as soon as possible.
Secondly, the basic design principles, the underlying principles of the basic components of big data, and the differences and connections between components with similar functions need to be gradually overcome.
Thirdly, the tuning ideas of components, understand the underlying principles and practice as soon as possible.
Finally, the classic project ideas and design patterns. Classic small algorithm idea.
