How do programmers find jobs? What if it becomes more and more difficult for programmers to find a job?

Recently, there have been a lot of news about layoffs in large Internet factories , The direct reason is still from performance pressure . For Internet companies , In the context of the obscene space growth of external companies . Want to improve performance , The most direct way is to lay off employees , So many people ask , How programmers find jobs ？ It's getting harder and harder to find a job ？ Let's talk about this today .

How programmers find jobs ？ It's getting harder and harder for programmers to find a job ？

From the demand distribution of programmers in the national Internet industry TOP15 In terms of their functions , The top three functions with the highest proportion of demand are Java、WEB Front-end development engineer 、 Mobile Development Engineer , Respectively 13.15%、9.46%、5.77%. The talent demand of Algorithm Engineers ranks fourth , Accounted for as 4.69%. With the breakthrough of computing power , Precipitation of big data , Artificial intelligence has become the hottest tuyere of the times , The demand for Algorithm Engineers is becoming more and more urgent , In the future, there will be greater demand for talents in this function .

In terms of programmer supply , The top three are the same as the talent demand , This means that these three functions are booming in both supply and demand in the Internet industry .

from IT For the whole industry , The group of beginners or programmers who can only engage in simple operations will indeed face many difficulties when looking for a job , But the experience is 3 In the above , Solid basic skills 、 Comprehensive ability is very strong 、 Programmers with rich experience in project practice , It is still a scarce resource in this industry , It is still the of various Internet companies “ Sweet steamed bun ”, Finding a well paid job is still no problem .

So those vendors are anxious , People who always say it's hard to find a job , Mostly because professional ability is not hard 、 Usually do not pay attention to learning and accumulation 、 No complete project experience . Selling anxiety can make your mood more and more negative , Unwilling or even afraid to find a job . To learn more 、 More than accumulation , Multi contact new technology , In order to take more initiative in the future competition .
