The perseverance and enthusiasm for learning in training institutions are not enough, and they can't persist.
Because I don't want to spend money, I don't want to change my major, I don't know the training content, and I don't trust the company.
You can go: if you change careers, you can only study again. There is no other good way.
After all, training is not going to school, it is quick and stressful.
Can be engaged in other industries, wages and development are different.
First, have a good attitude, firm confidence in winning, and be able to go all out to learn.
Don't go: you can save a little time, you don't have to learn from scratch, you can work directly.
If you plan to learn, the IT industry is good, you can go and have a look.
