Many fans commented in the background that the competition faced by Java programmers is too fierce... I also have a real feeling. I have been in the first-line Internet companies for many years. Although I have not faced the cruelty of job hunting and job hopping, I often serve as technical interview examiners. The status quo is clear. The reasons for the current fierce competition are nothing more than three aspects: there are too many people, the demand for technology is high, and there is no shortage of people in the middle and low-end positions...
