I want to go to Huaqing foresight training. Is it necessary?

Depends on what you think. Have you learned anything from self-study now? Whether it meets the enterprise employment standards depends on the recruitment website and what technology the company requires. If you hardly need training, if it doesn't work, you might as well go to the next place. Although you can't learn much from training, after all, you have a good learning environment and systematic learning methods, and you can enter this industry. No matter what industry is most important, study or after work, pre-training and study are all about laying the foundation, so you can get started faster after work, so training is still useful if you want to get started and work quickly, but if you want to learn some skills that are too deep or too high-end, forget it. After all, it is impossible to learn more in four months. Huaqing foresight is not bad in embedded training, which can be considered.
