Therefore, if you just want to find a job and train for a period of time, there will be no future in the future, because you can't get technical precipitation!
Personally, I suggest that you teach yourself, so that you can exercise one's ability, especially the ability to think independently.
In the Internet industry, the hottest industry is IT, so if you are ready, join it quickly.
In terms of technology, you can start with java. After all, it is simple and easy to get started, and if you learn well, your confidence in yourself will be greatly increased.
Of course, popular languages such as python, algorithms, artificial intelligence, and blockchain can also be used, but these thresholds are high and require algorithmic knowledge.
Learning algorithms requires knowledge of C, C++ and data structures, but these linguistics are very difficult, so it is best to learn from java.
If you don't know how to start, I can give you some advice.
Hope to adopt!
